Nursing Elites

1. When performing a health history on a patient who is to begin receiving a thiazide diuretic to treat heart failure, the nurse will be concerned about a history of which condition?

• A. Asthma
• B. Glaucoma
• C. Gout
• D. Hypertension

Correct answer: C

Rationale: Thiazide diuretics block uric acid secretion, leading to elevated levels that can contribute to gout. Therefore, patients with a history of gout should take thiazide diuretics with caution. Asthma (Choice A), Glaucoma (Choice B), and Hypertension (Choice D) are not directly contraindicated with thiazide diuretics, making choices A, B, and D incorrect.

2. A client has an elevated blood urea nitrogen (BUN)/creatinine ratio. Which action should the nurse take first?

• A. Assess the client’s dietary habits.
• B. Inquire about the client's use of nonsteroidal anti-inflammatory drugs (NSAIDs).
• C. Hold the client’s metformin (Glucophage).
• D. Contact the health care provider immediately.

Correct answer: A

Rationale: An elevated blood urea nitrogen (BUN)/creatinine ratio can indicate various conditions such as dehydration, urinary obstruction, catabolism, or a high-protein diet. The initial action the nurse should take is to assess the client’s dietary habits to determine if the elevated ratio is related to diet. Inquiring about the use of NSAIDs is important as they can impact kidney function, but dietary causes should be ruled out first. Holding metformin or contacting the health care provider without assessing the dietary habits would be premature actions as they may not address the underlying cause of the elevated BUN/creatinine ratio.

3. The nurse is caring for a 70-kg patient who is receiving gentamicin (Garamycin) 85 mg 4 times daily. The patient reports experiencing ringing in the ears. The nurse will contact the provider to discuss

• A. decreasing the dose to 50 mg QID.
• B. giving the dose 3 times daily.
• C. obtaining a serum drug level.
• D. ordering a hearing test.

Correct answer: C

Rationale: When a patient receiving gentamicin (Garamycin) reports experiencing ringing in the ears, it is crucial to consider the possibility of ototoxicity. Ototoxicity is a known adverse effect of aminoglycosides. The appropriate action for the nurse in this situation is to contact the provider to discuss obtaining a serum drug level. This is important to assess the drug concentration in the patient's blood, which can help determine if the ringing in the ears is related to the medication. Decreasing the dose or changing the dosing frequency without assessing the serum drug level may not address the underlying issue and could potentially lead to suboptimal treatment. Ordering a hearing test may be necessary at a later stage if the serum drug level indicates a concern. Therefore, option C, obtaining a serum drug level, is the most appropriate action to take in this scenario.

4. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

• A. To broaden the antibacterial spectrum.
• B. To decrease bacterial resistance.
• C. To improve the taste.
• D. To minimize toxic effects.

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

5. The healthcare provider notes a blood pressure of 160/90 mm Hg in a patient taking a thiazide diuretic. The patient reports taking an herbal medication that a friend recommended. Which herbal product is likely, given this patient’s blood pressure?

• A. Ginkgo
• B. Hawthorn
• C. Licorice
• D. St. John’s wort

Correct answer: A

Rationale: The correct answer is A: Ginkgo. Increased blood pressure can result when ginkgo is used in combination with a thiazide diuretic. Option B (Hawthorn) is incorrect because hawthorn is more commonly associated with lowering blood pressure. Option C (Licorice) is incorrect because licorice can lead to sodium and water retention, potentially exacerbating hypertension. Option D (St. John’s wort) is incorrect as it is not typically associated with significant blood pressure effects.
