Nursing Elites

1. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

2. A client with DM is taking regular and NPH insulin every morning. The nurse should provide which instruction to the client?

• A. Take the regular insulin first, then the NPH insulin.
• B. Take the NPH insulin first, then the regular insulin.
• C. Mix the insulins in a separate syringe.
• D. Take the regular insulin first and immediately follow it with the NPH insulin.

Correct answer: A

Rationale: The correct instruction for the client is to take the regular insulin first, then the NPH insulin. Regular insulin should be administered before NPH insulin to prevent contamination and maintain the potency of each insulin type. Choice B is incorrect because NPH insulin should not be taken before regular insulin. Mixing the insulins in a separate syringe, as suggested in choice C, is not recommended as it may alter the effectiveness of the insulins. Choice D is also incorrect as taking the regular insulin first and immediately following it with NPH insulin is not the recommended administration sequence.

3. A female client with hypothyroidism (myxedema) is receiving levothyroxine (Synthroid), 25 mcg P.O. daily. Which finding should Nurse Hans recognize as an adverse drug effect?

• A. Dysuria
• B. Leg cramps
• C. Tachycardia
• D. Blurred vision

Correct answer: C

Rationale: Tachycardia is a potential adverse effect of levothyroxine, indicating overmedication. Dysuria (painful urination) is not typically associated with levothyroxine. Leg cramps are not a common adverse effect of levothyroxine. Blurred vision is not a typical adverse effect of levothyroxine; instead, it may be a sign of other eye-related conditions or medication side effects.

4. A client with Cushing's syndrome is scheduled for surgery to remove an adrenal tumor. The nurse should monitor for which of the following complications postoperatively?

• A. Hyperglycemia
• B. Hypotension
• C. Hypokalemia
• D. Hyponatremia

Correct answer: B

Rationale: Postoperative hypotension is a common complication after adrenal tumor removal in a client with Cushing's syndrome. This occurs due to the sudden withdrawal of cortisol, which leads to a relative adrenal insufficiency state. Hyperglycemia (Choice A) is more common preoperatively due to excessive cortisol levels. Hypokalemia (Choice C) and Hyponatremia (Choice D) are also associated with Cushing's syndrome but are less likely to be immediate postoperative complications compared to hypotension.

5. A female client with physical findings suggestive of a hyperpituitary condition undergoes an extensive diagnostic workup. Test results reveal a pituitary tumor, necessitating a transsphenoidal hypophysectomy. The evening before the surgery, Nurse Jacob reviews preoperative and postoperative instructions provided to the client earlier. Which postoperative instruction should the nurse emphasize?

• A. You must lie flat for 24 hours after surgery.
• B. You must avoid coughing, sneezing, and blowing your nose.
• C. You must restrict your fluid intake.
• D. You must report ringing in your ears immediately.

Correct answer: B

Rationale: Following a transsphenoidal hypophysectomy, it is crucial to avoid activities such as coughing, sneezing, and blowing the nose to prevent an increase in intracranial pressure or the risk of cerebrospinal fluid leakage. Coughing, sneezing, or nose blowing can strain the surgical site, potentially leading to complications. Lying flat for 24 hours is not typically required after this surgery. Fluid intake should be encouraged to prevent dehydration. Ringing in the ears is not a common complication associated with this type of surgery.
