Question 1 of 5
The nurse is caring for a client diagnosed with type 1 diabetes mellitus. Because the client is at risk for hypoglycemia, which instructions should the nurse teach the client to follow?
Correct Answer: A
Rationale: Glucose tablets are taken if a hypoglycemic reaction occurs. Glucagon is also a medication that may be prescribed to be administered subcutaneously or intramuscularly if the client loses consciousness and is unable to take glucose by mouth. Glucagon releases glycogen stores and raises the blood glucose levels of hypoglycemic clients. Family members can be taught to administer this medication and possibly to prevent an emergency department visit. Acetone in the urine may indicate hyperglycemia. Although signs/symptoms of hypoglycemia need to be taught to the client, drowsiness is not the initial and key sign of this complication. The nurse should not instruct a client to omit insulin.
Question 2 of 5
A nurse is caring for a client who is post-op day #1 after a total hip replacement. Although the client was alert with a normal affect in the morning, by lunchtime, the nurse notes the client is confused, has slurred speech, and is having trouble with her balance. Her blood glucose level is 48 mg/dl. What is the next action of the nurse?
Correct Answer: D
Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (
Choice
B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (
Choice
C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (
Choice
A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.
Question 3 of 5
A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?
Correct Answer: A
Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (
Choice
B) are more commonly associated with hypocalcemia. Constipation (
Choice
C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (
Choice
D) is associated with hypokalemia, not hyperkalemia.
Question 4 of 5
Which of the following conditions may cause an increased respiratory rate?
Correct Answer: D
Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues.
To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen.
Stooped posture (
Choice
A) is not directly related to an increased respiratory rate. Narcotic analgesics (
Choice
B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (
Choice
C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.
Question 5 of 5
The nurse caring for a client in labor should plan to assess the fetal heart rate (FHR) at which specific times? Select all that apply.
Correct Answer: A,B,C,E
Rationale: Assessment of the mother and fetus is continuous during the process of labor. However, for all clients, the FHR needs to be assessed before ambulation; immediately after vaginal examinations, rupture of the membranes, or any other invasive procedure; and before the administration of oxytocin because these activities or situations can cause alterations in the FHR. The FHR is also assessed in between contractions, during the contraction, and for at least 30 seconds after the contraction. It is not necessary to assess the FHR before turning the client to her side.
