Nursing Elites

1. A client with diabetes mellitus visits a health care clinic. The client's diabetes mellitus was previously well controlled with daily glyburide (DiaBeta). However, the fasting blood glucose level has recently been in the range of 180 to 200 mg/dL. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?

• A. Prednisone
• B. Phenelzine (Nardil)
• C. Atenolol (Tenormin)
• D. Allopurinol (Zyloprim)

Correct answer: A

Rationale: Prednisone is known to reduce the effectiveness of oral hypoglycemic medications like glyburide and insulin, which can result in hyperglycemia. Therefore, the addition of prednisone to the client's regimen could have contributed to the elevated fasting blood glucose levels observed.

2. A client with type 2 diabetes mellitus is prescribed glipizide (Glucotrol). Which instruction should the nurse include in the teaching plan?

• A. Take the medication before a meal.
• B. Monitor for signs of hypoglycemia.
• C. Avoid alcohol consumption while taking this medication.
• D. Take the medication before bedtime.

Correct answer: B

Rationale: The correct instruction the nurse should include in the teaching plan for a client prescribed glipizide (Glucotrol) is to monitor for signs of hypoglycemia. Glipizide stimulates insulin release from the pancreas, which can lead to hypoglycemia. It is usually taken before a meal, not necessarily on an empty stomach. Alcohol consumption should be avoided to prevent interactions with the medication. Taking the medication before bedtime is not the typical recommendation.

3. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:

• A. Immediately before swimming
• B. 15 minutes before exposure to the sun
• C. Immediately before exposure to the sun
• D. At least 30 minutes before exposure to the sun

Correct answer: D

Rationale: Chemical sunscreens are most effective when applied at least 30 minutes before exposure to the sun to allow them to penetrate the skin and provide optimal protection. Applying sunscreen immediately before swimming (Choice A) or immediately before exposure to the sun (Choice C) may not provide sufficient time for the sunscreen to be absorbed and offer proper protection. Applying sunscreen 15 minutes before sun exposure (Choice B) is also not ideal as it may not allow enough time for the sunscreen to work effectively. Therefore, the correct answer is to apply chemical sunscreen at least 30 minutes before exposure to the sun to ensure it can be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.

4. When monitoring a client for acute toxicity associated with bethanechol chloride (Urecholine), what sign should the nurse check for to indicate toxicity?

• A. Dry skin
• B. Dry mouth
• C. Bradycardia
• D. Signs of dehydration

Correct answer: C

Rationale: The correct answer is C: Bradycardia. Toxicity from bethanechol chloride (Urecholine) can lead to excessive muscarinic stimulation, resulting in manifestations like salivation, sweating, involuntary urination and defecation, bradycardia, and severe hypotension. When facing toxicity, treatment involves supportive measures and administering atropine sulfate subcutaneously or intravenously.

5. A client with angina pectoris is experiencing chest pain that radiates down the left arm. The nurse administers a sublingual nitroglycerin tablet to the client. The client's pain is unrelieved, and the nurse determines that the client needs another nitroglycerin tablet. Which of the following vital signs is most important for the nurse to check before administering the medication?

• A. Temperature
• B. Respirations
• C. Blood pressure
• D. Radial pulse rate

Correct answer: C

Rationale: The correct answer is checking the client's blood pressure (C) before administering another nitroglycerin tablet. Nitroglycerin can cause hypotension, and monitoring blood pressure is crucial to prevent a sudden drop in blood pressure, especially when giving another dose of nitroglycerin.
