Nursing Elites

1. 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.

2. A nurse assesses a client who is recovering from a nephrostomy. Which assessment findings should alert the nurse to urgently contact the healthcare provider? (Select all that apply.)

• A. Foul-smelling drainage
• B. Bloody drainage at site
• C. A & B
• D. All of the above

Correct answer: C

Rationale: After a nephrostomy, the nurse should assess the client for complications and urgently notify the provider if there is foul-smelling drainage, bloody drainage at the site, or both. Foul-smelling drainage can indicate infection, while bloody drainage may suggest bleeding. Clear drainage is generally normal after a nephrostomy. A headache would not typically be directly related to nephrostomy complications. Therefore, options A and B are correct choices for urgent notification, making option C the correct answer.

3. A marathon runner comes into the clinic and states, 'I have not urinated very much in the last few days.' The nurse notes a heart rate of 110 beats/min and a blood pressure of 86/58 mm Hg. Which action by the nurse is the priority?

• A. Give the client a bottle of water immediately.
• B. Start an intravenous line for fluids.
• C. Teach the client to drink 2 to 3 liters of water daily.
• D. Perform an electrocardiogram.

Correct answer: A

Rationale: The priority action for the nurse is to give the client a bottle of water immediately. The athlete's symptoms of decreased urination, along with a heart rate of 110 beats/min and low blood pressure of 86/58 mm Hg, indicate mild dehydration. Rehydration should begin promptly to address the dehydration. Teaching the client to drink 2 to 3 liters of water daily is a good long-term strategy but not the immediate priority. Starting an intravenous line for fluids may be necessary if oral hydration is insufficient or if the degree of dehydration is severe. Performing an electrocardiogram is not indicated at this time as the priority is addressing the dehydration.

4. 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.

5. Which of the following is a key symptom of hypothyroidism?

• A. Weight loss.
• B. Heat intolerance.
• C. Cold intolerance.
• D. Increased appetite.

Correct answer: C

Rationale: Cold intolerance is a key symptom of hypothyroidism because a decreased metabolic rate leads to a reduced ability to regulate body temperature. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism, where excess thyroid hormone leads to an increased sensitivity to heat. Increased appetite (Choice D) is not typically seen in hypothyroidism; instead, individuals with hypothyroidism may experience weight gain due to the slowed metabolism.
