Correct Answer: A,B

Rationale: The goal of treatment of diabetic ketoacidosis (DK
A) is to normalize fluid volume, decrease blood glucose levels, balance electrolytes, and
correct metabolic acidosis. On administration of insulin, potassium and glucose shift from the extracellular space to the intracellular space.
Clients with DKA require potassium administration due to low intracellular potassium levels.
Insulin is administered to facilitate glucose transport into the intracellular space to resolve DKA and should be continued until the metabolic
acidosis resolves. When caring for clients with DKA, the nurse should anticipate:
• Adding 5% dextrose to continuous IV fluids when the serum blood glucose level reaches approximately 200 mg/dL (11.1 mmol/L) to
prevent hypoglycemia and cerebral edema resulting from levels decreasing too quickly (Option 1). This is done because insulin is still
required to resolve DKA. If the DKA is resolved, insulin can also be decreased instead of adding dextrose to the IV fluids.
• Administering potassium chloride for a client with hypokalemia and adequate urine output (ie, >30 mL/hr) to prevent life-threatening
arrhythmias

Correct Answer: B,D,F

Rationale: The client is most likely experiencing diabetes mellitus (DM) and requires blood glucose management to prevent
hyperglycemia.
A urinalysis positive for glucose and ketones are manifestations that should raise suspicion of DM. Ketones are produced
when the body cannot use glucose for energy and breaks down fat stores instead. Ketonuria is a sign of diabetic ketoacidosis
(DK
A), a life-threatening complication of DM. Clients with new-onset type 1 DM often present with DKA. Blood glucose
management in those with type 1 DM will require insulin administration.

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

Correct Answer:

Rationale: Appropriate interventions for the client with major depressive disorder who is experiencing suicidal ideation include the
following:
• Assigning the client to a shared room near the nurses' station to reduce social isolation and allow easier access to the
client
• Avoiding utensils on the client's meal tray that could be used for self-harm
• Checking on the client at frequent, irregular intervals (if not under 1-to-1 observation) to lessen predictability of staff
surveillance
• Performing frequent room searches for harmful objects to ensure client safety
• Performing mouth checks after medication administration to ensure the client has swallowed medication and is not
saving them for a future overdose attempt
• Encouraging the client to participate in grooming and hygiene because the client may exhibit loss of interest in daily
activities, decreased energy, and lack of motivation
Avoiding discussion of suicidal thoughts is not appropriate. Clients with suicidal ideation are often reluctant to disclose
their thoughts unless asked directly. The nurse should establish a nonjudgmental, therapeutic relationship that allows for open
communication.
It is not appropriate for the nurse to document that the client is not available for a safety check when the client is using the
restroom. The nurse must ensure that there is visual contact with the client during safety checks, even if the client is in the
restroom, to ensure safety.

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.
