Question 1 of 5

The following medications were noted on review of the client's home medication profile. Which of the medications would most likely potentiate or elevate serum digoxin levels?

Correct Answer: C

Rationale: Hypokalemia can cause digoxin toxicity. Administration of KCl would prevent this. Thyroid agents decrease digoxin levels. Quinidine increases digoxin levels dramatically. Theophylline is not noted to have an effect on digoxin levels.

Question 2 of 5

The nurse is caring for a client with a diagnosis of ectopic pregnancy. Which diagnostic test is most likely to be ordered?

Correct Answer: C

Rationale: Ultrasound confirms the location of the pregnancy (e.g. outside the uterus) and serial serum hCG levels help diagnose ectopic pregnancy by showing abnormal doubling patterns. Both tests are commonly ordered.

Question 3 of 5

The nurse is caring for a client with a suspected hip fracture. Which intervention should be implemented to prevent complications?

Correct Answer: C

Rationale: Immobilizing the hip with a splint prevents further injury and reduces pain in a suspected hip fracture. Heating pads, dependent positioning, and weight-bearing can worsen the injury.
