Nursing Elites

1. A client in the postanesthesia care unit has an as-needed prescription for ondansetron (Zofran). Which of the following occurrences would prompt the nurse to administer this medication to the client?

• A. Paralytic ileus
• B. Incisional pain
• C. Urine retention
• D. Nausea and vomiting

Correct answer: D

Rationale: The correct answer is D: Nausea and vomiting. Ondansetron is an antiemetic used to manage postoperative nausea and vomiting, as well as nausea and vomiting related to chemotherapy. It is not indicated for treating paralytic ileus, incisional pain, or urine retention. Paralytic ileus is a condition of the gastrointestinal tract characterized by the paralysis of intestinal muscles, which would not be treated with ondansetron. Incisional pain is typically managed with analgesics, not antiemetics. Urine retention is a urinary issue that does not involve nausea and vomiting, making ondansetron an inappropriate choice for this condition.

2. After a transsphenoidal hypophysectomy, the nurse should assess the client for:

• A. Cerebrospinal fluid (CSF) leak.
• B. Fluctuating blood glucose levels.
• C. Cushing's syndrome.
• D. Cardiac arrhythmias.

Correct answer: A

Rationale: Following a transsphenoidal hypophysectomy, assessing the client for a cerebrospinal fluid (CSF) leak is crucial due to the risk of this serious complication. A CSF leak can lead to infection and increased intracranial pressure, which must be promptly identified and managed to prevent further complications. Fluctuating blood glucose levels (Choice B) are not directly associated with a transsphenoidal hypophysectomy. Cushing's syndrome (Choice C) is a condition related to prolonged exposure to high levels of cortisol and is not a common immediate concern post-transsphenoidal hypophysectomy. Cardiac arrhythmias (Choice D) are not typically a direct complication of this surgical procedure, making it a less relevant concern compared to a CSF leak.

3. A patient has been taking spironolactone (Aldactone) to treat heart failure. The nurse will monitor for

• A. hyperkalemia.
• B. hypermagnesemia.
• C. hypocalcemia.
• D. hypoglycemia.

Correct answer: A

Rationale: The correct answer is A: hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in heart failure management. One of the major side effects of spironolactone is hyperkalemia, which is an elevated level of potassium in the blood. Monitoring for hyperkalemia is crucial as it can lead to serious cardiac arrhythmias. Choices B, C, and D are incorrect. Hypermagnesemia (choice B) is not typically associated with spironolactone use. Hypocalcemia (choice C) and hypoglycemia (choice D) are also not directly linked to the use of spironolactone in heart failure treatment.

4. After three days of persistent epigastric pain, a female client presents to the clinic. She has been taking oral antacids without relief. Her vital signs are heart rate 122 beats/minute, respirations 16 breaths/minute, oxygen saturation 96%, and blood pressure 116/70. The nurse obtains a 12-lead electrocardiogram (ECG). Which assessment finding is most critical?

• A. Irregular pulse rhythm
• B. Bile-colored emesis
• C. ST elevation in three leads
• D. Complaint of radiating jaw pain

Correct answer: C

Rationale: ST elevation in three leads is a critical finding that suggests myocardial infarction, requiring immediate attention. This finding indicates ischemia or injury to the heart muscle. Choices A, B, and D are not as critical in this scenario. Irregular pulse rhythm may be concerning but does not indicate an immediate life-threatening condition like myocardial infarction. Bile-colored emesis and complaint of radiating jaw pain are relevant but not as indicative of a myocardial infarction as ST elevation in three leads.

5. A client tells the nurse that he has been experiencing frequent heartburn and has been 'living on antacids.' For which acid-base disturbance does the nurse recognize a risk?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: B

Rationale: The correct answer is B: Metabolic alkalosis. In this scenario, the client's frequent use of antacids containing alkaline components can lead to an excess of bicarbonate in the body, causing metabolic alkalosis. Oral antacids work by neutralizing stomach acid, potentially leading to an alkaline shift in the body's pH balance. Choices A, C, and D are incorrect. Metabolic acidosis is not typically associated with antacid use. Respiratory acidosis and respiratory alkalosis are related to respiratory system dysfunction rather than antacid ingestion.
