1. Which lab value is critical for a patient on 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. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.

2. A nurse in an emergency department is caring for a client who reports cocaine use 1hr ago. Which of the following findings should the nurse expect?

A. Hypotension
B. Memory loss
C. Slurred speech
D. Elevated temperature

Correct answer: D

Rationale: The correct answer is D: Elevated temperature. Cocaine is a stimulant drug that can lead to an increase in body temperature. Hypotension (choice A) is less likely as cocaine tends to increase blood pressure. Memory loss (choice B) and slurred speech (choice C) are not typically immediate effects of recent cocaine use.

3. A nurse overhears two assistive personnel (AP) discussing care for a client in the elevator. What action should the nurse take?

A. Contact the client's family about the incident.
B. Notify the client's provider about the incident.
C. File a complaint with the ethics committee.
D. Report the incident to the AP's charge nurse.

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to report the incident to the AP's charge nurse. This ensures that the issue is addressed internally and allows for proper handling of the situation. Contacting the client's family about the incident (Choice A) may not be appropriate as it could breach confidentiality and escalate the situation unnecessarily. Notifying the client's provider (Choice B) is not the most immediate and effective step to address the issue. Filing a complaint with the ethics committee (Choice C) should be reserved for serious ethical violations, and in this case, reporting to the charge nurse is the more practical and immediate course of action.

4. What is the best method to assess pain in a non-verbal patient?

A. Observe for facial expressions
B. Observe for restlessness
C. Observe for sweating
D. Check for non-verbal cues

Correct answer: A

Rationale: The correct answer is to observe for facial expressions when assessing pain in a non-verbal patient. Facial expressions can provide vital clues about the patient's pain level and discomfort. Choices B and C, observing for restlessness and sweating, can be less specific and may indicate other issues besides pain. Choice D, checking for non-verbal cues, is too broad and does not specify the crucial aspect of focusing on facial expressions.

5. A nurse is reviewing the medical record of a client who has a history of myocardial infarction. Which of the following findings should the nurse report to the provider?

A. Blood pressure 140/90 mm Hg
B. Heart rate of 88/min
C. LDL cholesterol 110 mg/dL
D. Respiratory rate of 16/min

Correct answer: D

Rationale: In a client with a history of myocardial infarction, a respiratory rate of 16/min should be reported to the provider. Changes in respiratory rate can indicate cardiac or pulmonary issues that need further evaluation. The other vital signs provided (blood pressure, heart rate, and LDL cholesterol level) are within normal limits and do not directly relate to potential complications following a myocardial infarction.
