Nursing Elites

1. The client with diabetes mellitus should be cautioned by the nurse taking a sulfonylurea that alcoholic beverages should be avoided while taking these drugs because they can cause which of the following?

• A. Hypokalemia.
• B. Hyperkalemia.
• C. Hypocalcemia.
• D. Disulfiram (Antabuse)-like symptoms.

Correct answer: D

Rationale: The correct answer is D: Disulfiram (Antabuse)-like symptoms. When a client with diabetes mellitus taking a sulfonylurea consumes alcohol, it can lead to disulfiram-like symptoms, such as nausea, flushing, and palpitations. Choice A, hypokalemia, is incorrect because sulfonylureas do not typically lead to low potassium levels. Choice B, hyperkalemia, is incorrect as sulfonylureas are not associated with high potassium levels. Choice C, hypocalcemia, is also incorrect because sulfonylureas are not known to cause low calcium levels.

2. A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:

• A. Prevent fluid overload.
• B. Reduce the workload on the kidneys.
• C. Prevent dehydration.
• D. Maintain electrolyte balance.

Correct answer: B

Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.

3. A healthcare professional assesses clients on the medical-surgical unit. Which client is at greatest risk for the development of bacterial cystitis?

• A. A 36-year-old female who has never been pregnant
• B. A 42-year-old male who is prescribed cyclophosphamide
• C. A 58-year-old female who is not taking estrogen replacement
• D. A 77-year-old male with mild congestive heart failure

Correct answer: C

Rationale: Females are at higher risk of developing bacterial cystitis due to their shorter urethra compared to males. Postmenopausal women not on estrogen replacement therapy are particularly susceptible to cystitis because of changes in vaginal and urethral cells. This increases the risk of bacterial infection. The other options do not have the same level of risk as the postmenopausal woman not using hormone replacement therapy. A never-pregnant middle-aged woman does not have the same increased risk as a postmenopausal woman with hormonal changes.

4. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

• A. Compensated metabolic acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic alkalosis
• D. Uncompensated respiratory acidosis

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

5. The nurse is providing discharge teaching for a patient who will receive oral levofloxacin (Levaquin) to treat pneumonia. The patient takes an oral hypoglycemic medication and uses over-the-counter (OTC) antacids to treat occasional heartburn. The patient reports frequent arthritis pain and takes acetaminophen when needed. Which statement by the nurse is correct when teaching this patient?

• A. You may take antacids with levofloxacin to decrease gastrointestinal upset.
• B. You may take nonsteroidal anti-inflammatory medications (NSAIDs) for arthritis pain.
• C. You should monitor your serum glucose more closely while taking levofloxacin.
• D. You should take levofloxacin on an empty stomach to improve absorption.

Correct answer: C

Rationale: Levofloxacin may increase the effects of oral hypoglycemic medications, so patients taking these should be advised to monitor their serum glucose levels closely.
