NCLEX-PN Quizlet 2023 Questions
Question 1 of 5
What is the drug of choice for herpes simplex virus 1, herpes simplex virus 2, and varicella-zoster virus?
Correct Answer: B
Rationale: Acyclovir (Zovirax) is the drug of choice for herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), and varicella-zoster virus (VZV) infections. It works by inhibiting viral DNA replication. Acyclovir is excreted unchanged in the urine, so caution is needed in renal impairment. Choice A, HIV, is incorrect as acyclovir is not the drug of choice for HIV. Choice C, CMV, is incorrect as acyclovir is not the preferred treatment for cytomegalovirus (CMV) infections. Choice D, Influenza A viruses, is incorrect as acyclovir is not used to treat influenza viruses.
Question 2 of 5
A client begins a regimen of chemotherapy. Her platelet count falls to 98,000. Which action is least likely to increase the risk of hemorrhage?
Correct Answer: C
Rationale: The correct answer is to implement reverse isolation. Reverse isolation is a protective measure used to protect patients from infections, not to affect the risk of hemorrhage. Testing all excreta for occult blood (Choice A) is important to monitor for signs of internal bleeding. Using a soft toothbrush or foam cleaner for oral hygiene (Choice B) is recommended to prevent gum bleeding. Avoiding IM injections (Choice D) is crucial to reduce the risk of bleeding in a client with a low platelet count. Therefore, among the given options, implementing reverse isolation is the least likely to increase the risk of hemorrhage.
Question 3 of 5
A pregnant Asian client who is experiencing morning sickness wants to take ginger to relieve the nausea. Which of the following responses by the nurse is appropriate?
Correct Answer: A
Rationale: The correct response is to offer to consult with the physician regarding the use of ginger, showing cultural sensitivity. Ginger is known to help relieve nausea, especially in pregnancy. Choice A is the correct answer as it respects the client's preference for a home remedy and involves the physician in the decision-making process. Choice B dismisses the client's preference for a home remedy without exploring its potential benefits. Choice C makes a generalized statement discrediting the effectiveness of herbs, which is not evidence-based and disregards the client's beliefs. Choice D offers an alternative without addressing the client's specific request, failing to acknowledge the client's autonomy and cultural background.
Question 4 of 5
Signs of impaired breathing in infants and children include all of the following except:
Correct Answer: D
Rationale: Signs of impaired breathing in infants and children typically include nasal flaring, grunting, and seesaw breathing. Nasal flaring is the widening of the nostrils during breathing to help with air intake, grunting is a sound made during expiration to keep the airway open, and seesaw breathing is an abnormal pattern where the chest moves in while the abdomen moves out. Quivering lips are not a typical sign of impaired breathing in infants and children, making it the correct answer. Nasal flaring, grunting, and seesaw breathing are all signs indicating the need for immediate medical attention due to potential respiratory distress.
Question 5 of 5
A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?
Correct Answer: A
Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.
