Which of the following is a sign of digoxin toxicity?
- A. Bradycardia
- B. Hypertension
- C. Tachycardia
- D. Tachypnea
Correct Answer: A
Rationale: The correct answer is A, Bradycardia. Bradycardia, or a slower than normal heart rate, is a classic sign of digoxin toxicity. Digoxin is a medication commonly used to treat heart conditions, but an excess of digoxin in the body can lead to toxicity. This toxicity can manifest as various symptoms, with bradycardia being one of the most common ones. Hypertension (high blood pressure) and tachycardia (fast heart rate) are not typical signs of digoxin toxicity. Tachypnea, which refers to rapid breathing, is also not a common sign of digoxin toxicity.

Which of the following lab values should the nurse monitor for a patient receiving heparin therapy?
- A. Monitor platelet count
- B. Monitor PT/INR
- C. Monitor aPTT
- D. Monitor CBC
Correct Answer: C
Rationale: The correct answer is to monitor aPTT for a patient receiving heparin therapy. The activated partial thromboplastin time (aPTT) is used to assess and adjust heparin dosage to ensure the patient is within the therapeutic range for anticoagulation. Monitoring the aPTT helps in preventing both clotting and bleeding complications. Platelet count (Choice A) is important to monitor for patients receiving antiplatelet therapy, not heparin. PT/INR (Choice B) is typically monitored for patients on warfarin therapy, not heparin. Monitoring the complete blood count (CBC) (Choice D) is essential for various conditions but is not specific to monitoring heparin therapy.
A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Serum calcium
- B. Blood glucose
- C. Serum protein
- D. Serum albumin
Correct Answer: D
Rationale: The correct answer is D, Serum albumin. Serum albumin levels are a good indicator of the nutritional effectiveness of total parenteral nutrition (TPN). Monitoring serum albumin levels helps assess the client's overall protein status and nutritional adequacy. Choices A, B, and C are not direct indicators of the effectiveness of TPN therapy. Serum calcium levels may be affected by other factors, blood glucose monitoring is more relevant for clients with diabetes or those receiving insulin therapy, and serum protein is not as specific as serum albumin in evaluating TPN effectiveness.
A nurse is assessing a client who is postoperative following a thyroidectomy. Which of the following findings is the priority for the nurse to report?
- A. Calcium level of 9.0 mg/dL
- B. Serum sodium level of 138 mEq/L
- C. Respiratory rate of 18/min
- D. Stridor
Correct Answer: D
Rationale: Stridor is a high-pitched sound that indicates airway obstruction and is the priority finding to report following a thyroidectomy. In this situation, airway compromise is a critical concern that requires immediate intervention to ensure adequate oxygenation. While calcium level (Choice A) and serum sodium level (Choice B) are important assessments post-thyroidectomy, they do not represent an immediate threat to the client's airway. A respiratory rate of 18/min (Choice C) falls within the normal range and does not indicate an immediate risk to the client's airway compared to the presence of stridor.
What is the appropriate intervention for a patient with hypertension refusing medication?
- A. Educate the patient on the importance of medication
- B. Respect the patient's decision
- C. Inform the healthcare provider
- D. Explore alternative treatment options
Correct Answer: A
Rationale: The correct answer is A: Educate the patient on the importance of medication. Providing education to the patient is crucial in promoting understanding of the condition and the necessity of medication. By enhancing the patient's knowledge, healthcare providers can empower them to make informed decisions regarding their health. Choice B, respecting the patient's decision, may not be appropriate in this scenario as untreated hypertension can lead to serious complications. Choice C, informing the healthcare provider, is important but should be done after attempting to educate the patient. Choice D, exploring alternative treatment options, may be considered if the patient has concerns or side effects related to the medication, but initially, educating the patient about the importance of medication is key.
What is the priority nursing intervention for a patient experiencing a myocardial infarction?
- A. Administer aspirin
- B. Administer nitroglycerin
- C. Administer morphine
- D. Prepare for surgery
Correct Answer: A
Rationale: The correct answer is to administer aspirin. Administering aspirin is a priority nursing intervention for a patient experiencing a myocardial infarction because it helps reduce the risk of further clot formation. Aspirin is a common medication given during the early stages of a heart attack to prevent additional clotting. Administering nitroglycerin may also be indicated to help relieve chest pain by dilating blood vessels, but aspirin takes precedence due to its role in preventing clot progression. Administering morphine is not typically the first intervention in myocardial infarction as it can mask symptoms and delay other critical treatments. Surgery is not an immediate priority in the initial management of a myocardial infarction.
