1. 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.

2. What is the best intervention for a patient with dehydration?

A. Administer IV fluids
B. Provide oral fluids
C. Encourage fluid intake
D. Administer electrolytes

Correct answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

3. What is the primary purpose of administering an antiemetic?

A. To reduce nausea and vomiting
B. To increase appetite
C. To treat nausea caused by chemotherapy
D. To treat allergic reactions

Correct answer: A

Rationale: The correct answer is A: 'To reduce nausea and vomiting.' Antiemetics are medications used to prevent or alleviate nausea and vomiting. While they may indirectly help with appetite by reducing the unpleasant symptoms that can lead to decreased food intake, their primary purpose is not to increase appetite (Choice B). Choice C, 'To treat nausea caused by chemotherapy,' is partly correct as antiemetics are commonly used to manage chemotherapy-induced nausea, but this is not their exclusive purpose. Choice D, 'To treat allergic reactions,' is incorrect as antiemetics are not primarily used for treating allergic reactions.

4. A nurse is caring for a client who has a prescription for a low-sodium diet. Which of the following foods should the nurse recommend?

A. Pickles
B. Fresh vegetables
C. Canned soup
D. Smoked salmon

Correct answer: B

Rationale: Fresh vegetables are an excellent choice for clients on a low-sodium diet as they are naturally low in sodium. Pickles, canned soup, and smoked salmon are high in sodium and should be avoided by clients following a low-sodium diet. Pickles are pickled in a brine solution high in sodium, canned soup usually contains added salt for preservation, and smoked salmon is a processed food that typically has a high sodium content.

5. What is the initial action a healthcare provider should take for a patient with chest pain?

A. Administer oxygen
B. Administer nitroglycerin
C. Administer morphine
D. Prepare for surgery

Correct answer: A

Rationale: The correct initial action for a patient with chest pain is to administer oxygen. Chest pain can be caused by insufficient oxygenation, and providing oxygen helps alleviate the pain by increasing oxygen levels in the blood. Administering nitroglycerin or morphine may be appropriate based on the underlying cause of the chest pain, but oxygen should be given first to ensure the patient's oxygen supply is adequate. Surgery is not typically the initial intervention for chest pain.
