Nursing Elites

1. A client with chronic renal failure has a potassium level of 6.5 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement.
• B. Notify the healthcare provider immediately.
• C. Administer calcium gluconate.
• D. Restrict the client's potassium intake.

Correct answer: B

Rationale: A potassium level of 6.5 mEq/L indicates hyperkalemia, which can lead to life-threatening arrhythmias. The correct priority action for the nurse is to notify the healthcare provider immediately. Hyperkalemia requires prompt intervention to lower potassium levels and prevent complications. Administering a potassium supplement (Choice A) would worsen the condition. Administering calcium gluconate (Choice C) is a treatment option but is not the nurse's priority action. Restricting the client's potassium intake (Choice D) may be necessary but is not the immediate priority when facing a critical potassium level.

2. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw catheter in a circular motion

Correct answer: A

Rationale: The correct answer is to apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia, so it is essential to limit the suctioning time. Maintaining sterile technique (choice B) is important to prevent infections but is not directly related to preventing hypoxia during suctioning. Lubricating the catheter tip (choice C) helps with insertion but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not help prevent hypoxia.

3. During the admission assessment of a 3-year-old with bacterial meningitis and hydrocephalus, which assessment finding is evidence of increased intracranial pressure (ICP)?

• A. Low blood pressure
• B. Increased respiratory rate
• C. Normal pupil reaction
• D. Sluggish and unequal pupillary responses

Correct answer: D

Rationale: Sluggish and unequal pupillary responses are indicative of increased intracranial pressure (ICP) in a child with bacterial meningitis and hydrocephalus. This finding suggests that the optic nerve is being compressed due to increased ICP, causing a delay in pupillary reactions. Such a delay is a critical sign of worsening ICP and necessitates immediate intervention. Low blood pressure and increased respiratory rate can occur in various conditions but are less specific to increased ICP than sluggish and unequal pupillary responses, which directly reflect neurological compromise.

4. The nurse is teaching a group of women about osteoporosis and exercise. The nurse should emphasize the need for which type of regular activity?

• A. Weight-bearing exercise
• B. Aerobic exercise
• C. Low-impact exercises such as swimming
• D. Stretching and flexibility exercises

Correct answer: A

Rationale: The correct answer is A: Weight-bearing exercise. Weight-bearing exercise helps build and maintain bone density, which is critical in preventing osteoporosis. Activities like aerobic exercises, stretching, and low-impact exercises such as swimming are beneficial for overall fitness but do not directly contribute to improving bone strength, making them less effective in preventing osteoporosis.

5. A client with heart failure has a prescription for digoxin. The nurse is aware that sufficient potassium should be included in the diet because hypokalemia in combination with this medication ____________.

• A. Can predispose to dysrhythmias
• B. May lead to oliguria
• C. May cause irritability and anxiety
• D. Sometimes alters consciousness

Correct answer: A

Rationale: The correct answer is A: Can predispose to dysrhythmias. Hypokalemia combined with digoxin increases the risk of dysrhythmias due to the potentiation of digoxin's effects on cardiac conduction. Choice B, May lead to oliguria, is incorrect because hypokalemia is not typically associated with oliguria. Choice C, May cause irritability and anxiety, is incorrect as these symptoms are more commonly associated with hypocalcemia. Choice D, Sometimes alters consciousness, is incorrect as altered consciousness is not a typical effect of hypokalemia combined with digoxin.
