Nursing Elites

1. A healthcare provider is assessing a client who is taking levothyroxine. The healthcare provider should recognize that which of the following findings is a manifestation of levothyroxine overdose?

• A. Insomnia
• B. Constipation
• C. Drowsiness
• D. Hypoactive deep-tendon reflexes

Correct answer: A

Rationale: Insomnia is a common symptom of levothyroxine overdose due to excessive stimulation of the central nervous system. Levothyroxine is a thyroid hormone replacement medication, and an overdose can lead to hyperthyroidism symptoms, including insomnia. Constipation and drowsiness are not typically associated with levothyroxine overdose. Hypoactive deep-tendon reflexes are more indicative of hypothyroidism rather than an overdose of levothyroxine.

2. A client is undergoing preparation for extensive colorectal surgery. Which of the following oral antibiotics should be administered to suppress normal flora in the GI tract?

• A. Kanamycin
• B. Gentamicin
• C. Neomycin
• D. Tobramycin

Correct answer: C

Rationale: The correct answer is C: Neomycin. Neomycin, an aminoglycoside antibiotic, is administered orally before GI surgery to eliminate the normal flora in the large intestine. This helps reduce the risk of postoperative infections by decreasing the bacterial load in the gut. Choices A, B, and D (Kanamycin, Gentamicin, Tobramycin) are not typically used to suppress normal flora in the GI tract before colorectal surgery.

3. A client has been prescribed diltiazem (Cardizem) and asks the nurse what type of drug this is. Which response by the nurse is most appropriate?

• A. “A beta blocker.”
• B. “A sodium channel blocker.”
• C. “An alpha blocker.”
• D. “A calcium channel blocker.”

Correct answer: D

Rationale: Diltiazem (Cardizem) belongs to the class of drugs known as calcium channel blockers. These medications work by blocking calcium from entering the muscle cells of the heart and blood vessels, leading to relaxation of the blood vessels and reduced workload on the heart. This helps in lowering blood pressure and improving blood flow. It is crucial for the nurse to provide accurate information to the client about the type of drug prescribed to ensure understanding and compliance with the treatment plan.

4. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?

• A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
• C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• D. Draw a peak level at 0900 and a trough level at 2100.

Correct answer: C

Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.

5. Which of the following drugs is associated with extreme photosensitivity as a reaction?

• A. Digitalis
• B. Niacin
• C. Tetracycline
• D. Fluoroquinolones

Correct answer: C

Rationale: Tetracycline is known to cause extreme photosensitivity reactions, making individuals more sensitive to sunlight and increasing the risk of severe sunburn. It is essential for patients taking tetracycline to protect themselves from excessive sun exposure to prevent adverse reactions.
