Nursing Elites

1. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?

• A. First-degree AV block.
• B. Premature ventricular contraction.
• C. Sinus bradycardia.
• D. Atrial fibrillation.

Correct answer: A

Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.

2. A nurse is teaching a client who has a new prescription for nitroglycerin sublingual tablets. Which of the following statements should the nurse include?

• A. "You can take this medication with a full glass of water."
• B. "You should store this medication in the refrigerator."
• C. "Take one tablet every 5 minutes until the pain is relieved, up to three doses."
• D. "You should avoid eating foods high in sodium while taking this medication."

Correct answer: C

Rationale: The correct statement the nurse should include is to take one nitroglycerin sublingual tablet every 5 minutes until the pain is relieved, up to three doses. This dosing regimen is important to manage angina attacks effectively. Option A is incorrect because nitroglycerin sublingual tablets should not be taken with water. Option B is incorrect as nitroglycerin tablets should be stored in their original container at room temperature. Option D is incorrect because there is no specific instruction to avoid foods high in sodium while taking nitroglycerin sublingual tablets.

3. A nurse is providing teaching about digoxin administration to the parents of a toddler with heart failure. Which of the following statements should the nurse include?

• A. Limit your child's potassium intake while taking this medication.
• B. You can mix the medication with a half-cup of your child's favorite juice.
• C. Do not repeat the dose if your child vomits within one hour after taking the medication.
• D. Have your child drink a small glass of water after swallowing the medication.

Correct answer: D

Rationale: The correct statement to include in the teaching about digoxin administration is to have the child drink a small glass of water after swallowing the medication. Water helps flush down the medication, preventing irritation in the esophagus. Choice A is incorrect because digoxin may interact with potassium levels, but strict restriction is not necessary. Choice B is incorrect as medications should not be mixed with juices unless specified by the healthcare provider due to possible interactions. Choice C is incorrect because if a child vomits after taking digoxin, the dose should not be repeated to avoid double dosing.

4. Which lab value should be monitored in patients receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.

5. A nurse is assessing a client who has pneumonia. Which of the following findings should the nurse expect?

• A. Bradycardia
• B. Crackles in the lung bases
• C. Dependent edema
• D. Productive cough

Correct answer: C

Rationale: Dependent edema is a common finding in clients with pneumonia due to fluid retention and decreased mobility. Bradycardia (Choice A) is not typically associated with pneumonia. Crackles in the lung bases (Choice B) are more commonly heard in conditions like heart failure or pulmonary edema. A productive cough (Choice D) can be seen in pneumonia but is not as specific as dependent edema.
