NCLEX PN 2023 Quizlet

1. Acyclovir is the drug of choice for:

A. HIV
B. HSV 1 and 2 and VZV
C. CMV
D. influenza A viruses

Correct answer: C

Rationale: Acyclovir (Zovirax) is specifically used to treat infections caused by herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and varicella-zoster virus (VZV). These include conditions like cold sores, genital herpes, and shingles. Acyclovir works by inhibiting viral DNA replication, leading to the formation of shorter, ineffective DNA chains. It is important to note that acyclovir is not effective against other viruses like HIV, cytomegalovirus (CMV), or influenza A viruses. Therefore, the correct answer is HSV 1 and 2 and VZV.

2. An RN on your unit has had an argument with the family of a client regarding the way in which the RN has changed the client's dressing. The family is adamant that the dressing change was performed incorrectly. The RN insists that sterile technique was observed. As an RN manager, what is the best response?

A. Meet with the family member and the RN to discuss the disagreement regarding the dressing change.
B. Talk to the family member and assure them that the nurse followed the hospital procedure.
C. Discuss the dressing change procedure with the RN and compare it to a current textbook.
D. Change the RN's assignment the next day to another client.

Correct answer: A

Rationale: When conflict occurs, it is best to meet with both parties together to discuss the problem. This approach allows each party to hear what the other is saying and prevents the RN manager from being caught in the middle. By facilitating a discussion between the family member and the RN, they can work together to find a resolution or the manager can mediate. This promotes open communication, understanding, and collaboration. Option A is the correct choice because it emphasizes addressing the conflict directly and seeking a mutual understanding. Option B is incorrect because just assuring the family member may not address the underlying issues. Option C is incorrect as it does not involve the family member in the resolution process. Option D is inappropriate as it doesn't address the conflict but rather avoids it by changing the RN's assignment.

3. The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:

A. Manage peripheral edema
B. Improve right ventricular function
C. Increase pulmonary pressure
D. Constrict the pulmonary vessels

Correct answer: B

Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.

4. A healthcare professional is reviewing a patient's serum glucose levels. Which of the following scenarios would indicate abnormal serum glucose values for a 30-year-old male?

A. 70 mg/dL
B. 55 mg/dL
C. 110 mg/dL
D. 100 mg/dL

Correct answer: B

Rationale: The correct answer is 55 mg/dL. The standard range for serum glucose levels is typically 60-115 mg/dL. A serum glucose level of 55 mg/dL falls below this range, indicating hypoglycemia. Options A, C, and D are within the standard range for serum glucose levels and would not be considered abnormal for a 30-year-old male.

5. After applying oxygen using bi-nasal prongs to a client who is having chest pain, the nurse should implement which intervention?

A. Have the client take slow deep breaths in through their mouth and out through their nose.
B. Post signs indicating that oxygen is in use on the client's door and in their room
C. Apply Vaseline petroleum to both nares and 2 by 2 gauze around the oxygen tubing at the client's ears
D. Encourage the client to hyperextend the neck, take a few deep breaths and cough.

Correct answer: A

Rationale: After applying oxygen using bi-nasal prongs to a client with chest pain, it is essential for the nurse to post signs indicating that oxygen is in use on the client's door and in their room. This safety precaution alerts healthcare providers and visitors that the client is receiving oxygen therapy, reducing the risk of accidents or misunderstandings. Choice A is incorrect because instructing the client to take slow deep breaths is not the appropriate intervention after applying oxygen. Choice C suggests applying Vaseline and gauze, which is unnecessary and not a standard practice. Choice D advising the client to hyperextend the neck, take deep breaths, and cough is not indicated after applying oxygen therapy and could potentially be harmful.
