Nursing Elites

1. The nurse is preparing to administer the first dose of hydrochlorothiazide (HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The nurse will perform which action?

• A. Administer the medication as ordered.
• B. Encourage the patient to drink more fluids.
• C. Hold the medication and request an order for serum BUN and creatinine.
• D. Request an order for serum electrolytes and administer the medication.

Correct answer: C

Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.

2. A client is receiving a continuous infusion of normal saline at 125 ml/hour post abdominal surgery. The client is drowsy and complaining of constant abdominal pain and a headache. Urine output is 800 ml over the past 24 hours with a central venous pressure of 15 mmHg. The nurse notes respiratory crackles and bounding central pulse. Vital signs: temperature 101.2 F (38.4 C), heart rate 96 beats/minute, respiration 24 breaths/minute, and blood pressure of 160/90 mmHg. Which intervention should the nurse implement first?

• A. Calculate total intake and output for the last 24 hours.
• B. Administer a PRN dose of acetaminophen.
• C. Decrease IV fluids to a keep vein open (KVO) rate.
• D. Review the last administration of IV pain medication.

Correct answer: C

Rationale: In this scenario, the client is showing signs of fluid volume excess, such as drowsiness, abdominal pain, headache, crackles in the lungs, bounding pulse, and elevated blood pressure. Decreasing the IV fluids to a keep vein open (KVO) rate is crucial to prevent further fluid overload. This intervention helps in balancing fluid intake and output to prevent complications associated with fluid volume excess. Calculating total intake and output (Choice A) may be necessary but not the immediate priority in managing fluid overload. Administering acetaminophen (Choice B) may help with managing the fever but does not address the underlying issue of fluid overload. Reviewing the last administration of IV pain medication (Choice D) is not the priority in this situation where fluid overload is a concern.

3. A client is to have a transsphenoidal hypophysectomy to remove a large, invasive pituitary tumor. The nurse should instruct the client that the surgery will be performed through an incision in the:

• A. Back of the mouth.
• B. Nose.
• C. Sinus channel below the right eye.
• D. Upper gingival mucosa in the space between the upper gums and lip.

Correct answer: D

Rationale: The correct answer is D: Upper gingival mucosa in the space between the upper gums and lip. A transsphenoidal hypophysectomy involves accessing the pituitary gland through an incision in the upper gingival mucosa, providing direct access to the pituitary gland without external scars. Choices A, B, and C are incorrect because the surgery is not performed through the back of the mouth, the nose, or the sinus channel below the right eye. It is crucial for the client to understand the specific location of the incision to ensure accurate preoperative education and expectations.

4. A patient has begun taking spironolactone (Aldactone) in addition to a thiazide diuretic. With the addition of the spironolactone, the nurse will counsel this patient to

• A. not take a potassium supplement daily.
• B. recognize that abdominal cramping is a common side effect.
• C. report decreased urine output to the provider.
• D. take these medications in the morning.

Correct answer: C

Rationale: When combining a potassium-sparing diuretic like spironolactone with a thiazide diuretic, there is an increased risk of hyperkalemia, especially in patients with poor renal function. Therefore, the patient should be educated to report any decrease in urine output, which could indicate a potential issue with kidney function. Choice A is incorrect because taking additional potassium supplements can further increase the risk of hyperkalemia. Choice B is incorrect as abdominal cramping is not a common side effect of spironolactone. Choice D is incorrect because the timing of medication administration is not directly related to the addition of spironolactone and thiazide diuretic; there is no specific recommendation to take these medications only at bedtime.

5. A serum phenytoin determination is prescribed for a client with a seizure disorder who is taking phenytoin (Dilantin). Which result indicates that the prescribed dose of phenytoin is therapeutic?

• A. 3 mcg/mL
• B. 8 mcg/mL
• C. 16 mcg/mL
• D. 28 mcg/mL

Correct answer: C

Rationale: The correct answer is 16 mcg/mL (Choice C). The therapeutic serum phenytoin range is typically 10 to 20 mcg/mL. A level below this range may lead to continued seizure activity, indicating subtherapeutic levels. Choices A, B, and D are below the therapeutic range and would not be considered therapeutic for a client with a seizure disorder on phenytoin therapy.
