1. Which electrolyte imbalance is most concerning in a patient taking digoxin?

A. Monitor potassium levels
B. Monitor calcium levels
C. Monitor sodium levels
D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

2. What is the best intervention for a patient experiencing hypoxia?

A. Administer oxygen
B. Reposition the patient
C. Provide humidified air
D. Provide chest physiotherapy

Correct answer: A

Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

3. A nurse is preparing to mix NPH and regular insulin in the same syringe. Which of the following actions should the nurse take?

A. Inject air into the NPH insulin vial.
B. Withdraw the prescribed dose of regular insulin.
C. Withdraw the prescribed dose of NPH insulin.
D. Mix the two insulins in separate syringes.

Correct answer: A

Rationale: When mixing NPH and regular insulin in the same syringe, the nurse should first inject air into the NPH insulin vial. This action prevents contamination by allowing an easier withdrawal of the correct dose of NPH insulin after withdrawing the regular insulin. Withdrawing the prescribed dose of regular insulin (Choice B) is incorrect as it does not address the initial step of injecting air into the NPH vial. Similarly, withdrawing the prescribed dose of NPH insulin (Choice C) is incorrect as it skips the crucial first step. Mixing the two insulins in separate syringes (Choice D) is not ideal since combining them in one syringe is a common practice to reduce the number of injections for the patient.

4. In an emergency department following a community disaster, a healthcare provider is performing triage for multiple clients. To which of the following types of injuries should the provider assign the highest priority?

A. Below-the-knee amputation.
B. Fractured tibia.
C. 95% full-thickness body burn.
D. 10 cm laceration to the forearm.

Correct answer: A

Rationale: During disaster triage, clients with severe injuries that are immediately life-threatening and have a high likelihood of mortality without intervention are assigned the highest priority. A below-the-knee amputation falls into this category as it indicates a critical injury that requires immediate attention to prevent further complications or loss of life. Fractured tibia, a 95% full-thickness body burn, and a 10 cm laceration to the forearm, while serious, do not pose the same level of immediate life-threatening risk as a below-the-knee amputation in the context of disaster triage.

5. A client who is at 30 weeks of gestation and is scheduled for a nonstress test is being taught by a nurse. Which of the following statements by the client indicates an understanding of the teaching?

A. I should avoid drinking fluids during the test.
B. I will need to drink a sugar solution before the test.
C. This test will monitor how my baby is responding to contractions.
D. This test will assess for fetal lung maturity.

Correct answer: B

Rationale: The correct answer is B because the client should drink a sugar solution for a glucose challenge test, which is part of the nonstress test protocol during pregnancy. Choice A is incorrect because adequate hydration is generally recommended before the test. Choice C is incorrect as the nonstress test monitors the baby's heart rate in response to its own movements, not contractions. Choice D is incorrect as the nonstress test does not assess fetal lung maturity.
