Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypocalcemia. Which of the following findings should the nurse expect?

• A. Positive Trousseau's sign
• B. Increased deep tendon reflexes
• C. Hyperactive bowel sounds
• D. Weak, thready pulse

Correct answer: A

Rationale: A positive Trousseau's sign is a key finding in clients with hypocalcemia, indicating neuromuscular irritability. The other choices are not typically associated with hypocalcemia. Increased deep tendon reflexes are more indicative of hypercalcemia. Hyperactive bowel sounds can be seen in hyperactive bowel conditions or diarrhea, not specifically related to hypocalcemia. A weak, thready pulse may indicate cardiovascular issues, such as dehydration, but it is not a typical finding in hypocalcemia.

2. What lab value should a healthcare provider monitor for a patient on warfarin therapy?

• A. Potassium
• B. PT/INR
• C. Sodium
• D. Calcium

Correct answer: B

Rationale: The correct answer is B: PT/INR. When a patient is on warfarin therapy, healthcare providers monitor the PT/INR levels to evaluate the effectiveness of the treatment and assess the risk of bleeding. Monitoring potassium, sodium, or calcium levels is not directly related to warfarin therapy and would not provide the necessary information needed to manage the medication effectively.

3. A healthcare provider is reviewing the laboratory report of a client with a prescription for digoxin. Which result requires withholding the medication?

• A. Digoxin 0.8 ng/mL
• B. Sodium 145 mEq/L
• C. BUN 20 mg/dL
• D. Potassium 3.1 mEq/L

Correct answer: D

Rationale: The correct answer is D. A low potassium level (3.1 mEq/L) can increase the risk of digoxin toxicity. Hypokalemia can potentiate the effects of digoxin on the heart, leading to serious dysrhythmias. Choices A, B, and C are within normal ranges and do not indicate a need to withhold digoxin.

4. A nurse is preparing to insert an indwelling urinary catheter for a client. Which of the following actions should the nurse take?

• A. Insert the catheter 7.5 cm (3 in) into the urethra.
• B. Insert the catheter until urine flow is established.
• C. Cleanse the catheter with sterile water before insertion.
• D. Insert the catheter 5 cm (2 in) into the urethra.

Correct answer: B

Rationale: The correct action for the nurse is to insert the catheter until urine flow is established. This helps ensure proper placement and reduces the risk of trauma. Choice A (7.5 cm) and Choice D (5 cm) provide specific measurements that may not be appropriate for all individuals as catheter insertion depth can vary. Choice C is incorrect as catheters should be cleansed with an appropriate solution such as sterile saline, not sterile water.

5. A nurse is planning discharge teaching about cord care for the parents of a newborn. Which of the following instructions should the nurse include?

• A. The cord stump will fall off in 5 days.
• B. Contact the provider if the cord stump turns black.
• C. Clean the base of the cord with hydrogen peroxide daily.
• D. Keep the cord stump dry until it falls off.

Correct answer: D

Rationale: The correct instruction for cord care is to keep the cord stump dry until it falls off. This helps prevent infection and promotes healing. Choice A is incorrect because the timing of when the cord stump falls off can vary, usually between 1-3 weeks. Choice B is incorrect as a black cord stump can be a normal part of the healing process, so it is unnecessary to contact the provider for this reason. Choice C is incorrect because cleaning the cord with hydrogen peroxide daily is not recommended as it can delay healing and cause irritation.
