Question 1 of 5
The nurse has reviewed the information from the Nurses' Notes, Vital Signs, and Laboratory Results.The nurse is reviewing the client's response to potassium-lowering therapies. Which finding is unexpected and requires follow-up by the nurse?
Correct Answer: A
Rationale: Treatment for hyperkalemia includes administration of calcium gluconate, furosemide, albuterol nebulizer, and insulin with dextrose. These
therapies may cause rapid shifts in fluid volume, blood glucose, and serum electrolytes. Insulin shifts available glucose and potassium into
the cell, lowering serum potassium levels; however, too much insulin and not enough dextrose cause hypoglycemia (eg, blood glucose 50
mg/dL [2.7 mmol/L]). Clients with kidney disease have an increased risk of hypoglycemia because insulin may accumulate.
The nurse should understand that a low blood glucose level and symptoms suspicious for hypoglycemia (eg, diaphoresis) require follow-u
to prevent seizures, coma, and death due to lack of circulating glucose (Option 1). This client requires an additional dose of dextrose.
(Option 2) This client's blood pressure is 146/88 mm Hg and heart rate is within normal limits. This is an improvement from the initial blood
pressure and represents a therapeutic response to furosemide administration. Blood pressure should be lowered slowly to avoid hypotensior

Question 2 of 5
The nurse has reviewed the information from the Laboratory Results. The nurse suspects that the client may have hyperemesis gravidarum. Which of the following findings support this diagnosis? Select a that apply.
Correct Answer: A,B,D,E
Rationale: Hyperemesis gravidarum (HG) is characterized by severe, persistent nausea and vomiting during pregnancy and weight loss of 25% of
prepregnancy weight. The exact cause of HG is unknown, but it is believed that pregnancy-related increases in hormone levels (eg, human
chorionic gonadotropin [hCG]) contribute to the condition. Laboratory findings that assist with the diagnosis of HG include:
• Elevated hematocrit level reflects hemoconcentration, which occurs due to dehydration from excessive vomiting and decreased fluid
intake (Option 1).
• Hypokalemia occurs due to excessive loss of potassium via vomiting and/or insufficient intake of potassium (Option 2).
• Ketonuria (ie, the presence of ketones in urine) results from the metabolism of fat for energy due to a lack of nutritional intake (Option
4).
• High urine specific gravity reflects the concentration of urine; concentrated urine may indicate that the client's volume is depleted,
which is common in HG (Option 5).

History and Physical
Body System, Finding
General,
Client is brought to the emergency department due to nausea, vomiting, and abdominal pain that began 24 hr
ago. Client has type 1 diabetes mellitus and usually takes insulin. Parents state that the client was at an
overnight camp for the past 4 days and are unsure of how much insulin the client has been taking.
Neurological,
Client is lethargic but arousable to voice. The pupils are equal, round, and reactive to light and accommodation.
Integumentary,
Mucous membranes are dry, skin turgor is poor.
Pulmonary,
Vital signs are RR 36 and SpOz 95% on room air. Lung sounds are clear to auscultation. Deep respirations and a
fruity odor on the breath are noted.
Cardiovascular,
Vital signs are T 98.4 F (36.9 C), P 110, and BP 98/58. Pulses are 3+ on all extremities, and capillary refill time is
4 sec.
Gastrointestinal Normoactive bowel sounds are heard in all 4 quadrants; the abdomen is nontender.
Genitourinary,
Client voided dark yellow urine.
Endocrine,
Client is prescribed levothyroxine daily for hypothyroidism and has missed one dose of levothyroxine.
Psychosocial,
Parents state that the client has been sad and slightly withdrawn for the past 2 weeks after ending a romantic relationship.
Question 3 of 5
Select 4 clinical findings that require immediate follow-up.
Correct Answer: A,B,C,E
Rationale: Type 1 diabetes mellitus is an endocrine disorder characterized by the absence of insulin production in the pancreas. Glucose requires insulin
to be transported from the extracellular space into the cell. Without insulin, glucose continues to circulate in the extracellular space, causing
serum hyperglycemia and intracellular glucose starvation that can lead to diabetic ketoacidosis (DK
A).
In DKA, the body breaks down fat for energy (ie, ketosis). This leads to high levels of ketones in the blood, which can cause life-threatening
metabolic acidosis. Clinical findings concerning for DKA require immediate follow-up and include:
• Nausea, vomiting, and abdominal pain—a common presentation of DKA (especially in children) that can be related to delayed gastric
emptying and/or ileus from electrolyte abnormalities and metabolic acidosis
• Neurologic symptoms (eg, lethargy, obtundation) due to progressive hyperglycemia and acidosis
• Signs of dehydration (eg, dry mucous membranes, prolonged P3 sec] capillary refill time) due to osmotic water loss caused by
glucose in the urine

Question 4 of 5
For each potential prescription, click to specify whether the prescription is expected or not expected for the care of the client.
| Potential Prescription | Expected | Not expected |
|---|---|---|
| Administer IV antibiotics | ||
| Prepare client for echocardiography | ||
| Initiate low-flow supplemental oxygen | ||
| Gather supplies for pericardiocentesis | ||
| Place peripherally inserted central catheter (PICC) | ||
| Collect a blood specimen for culture and sensitivity |
Correct Answer:
Rationale: Expected prescriptions for clients with suspected infective endocarditis (IE) include:
• Administering IV antibiotics to kill the infectious pathogen
• Preparing the client for echocardiography to identify valvular dysfunction, chamber enlargement, and vegetations
• Placing a peripherally inserted central catheter for long-term IV antibiotic therapy
• Collecting a blood specimen for culture and sensitivity to identify the infectious pathogen
Initiating low-flow supplemental oxygen is not expected because the client is not exhibiting signs of respiratory distress.
Pericardiocentesis is performed to remove excess fluid from the pericardial cavity and prevent progression to cardiac
tamponade. Pericardial effusions are not commonly expected with IE. Furthermore, this client is not exhibiting signs of
pericardial effusion (eg, muffled heart sounds, substernal pain).
Therefore, gathering supplies for pericardiocentesis is not
expected.

Nurses' Notes
Outpatient Clinic
Initial
visit
The child recently started attending a new preschool and hit a teacher during lunch. The parent says,
"My
child has never been aggressive before but has always been particular about food."
The client was born at full term without complications and has no significant medical history. The child
started babbling at age 6 months, and the parent reports that the first words were spoken around age 12
months. The client then became quiet and "obsessed" with stacking blocks and organizing toys by color.
The child can kick a ball, draw a circle, pedal a tricycle, and now says two-word phrases. Vitals signs are
normal, and the client is tracking adequately on growth curves.
During the evaluation, the child sits in the corner of the room playing with blocks. The client does not follow
the parents gaze when the parent points to toys in the office. The child begins screaming and rocking back
and forth when the health care provider comes near.

Question 5 of 5
For each finding below, click to specify if the finding is consistent with the expected action of the medication carvedilol, enalapril, or furosemide. Each finding may support more than one medication.
| Finding | Carvedilol | Enalapril | Furosemide |
|---|---|---|---|
| Decreases heart rate | |||
| Increases urinary output | |||
| Decreases blood pressure | |||
| Increases oxygen saturation |
Correct Answer:
Rationale: Pharmacologic management of heart failure (HF) focuses on reducing cardiac workload and improving cardiac output.
• Beta-adrenergic antagonists ("beta blockers") (eg, carvedilol) reduce cardiac workload by inhibiting the action of
catecholamines (eg, epinephrine, norepinephrine) on beta-adrenergic receptors in the heart. Beta blockers decrease
myocardial oxygen demand by decreasing blood pressure and decreasing heart rate.
• Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril) alter the renin-angiotensin-aldosterone system by
inhibiting conversion of angiotensin I to angiotensin II, thereby preventing the release of aldosterone. Aldosterone, an
adrenal steroid hormone, retains sodium and water in addition to promoting vasoconstriction. By reducing circulating
aldosterone, ACE inhibitors promote vasodilation and as a result decrease blood pressure. ACE inhibitors also
decrease ventricular remodeling, an added benefit for clients with HF.
• Loop diuretics (eg, furosemide) prevent reabsorption of sodium and chloride in the kidneys, which increases urine
output and fluid excretion. Decreases in circulating fluid volume will decrease blood pressure and reduce pulmonary
edema (ie, increase oxygen saturation), as well as decrease cardiac preload.
