NCLEX-PN Quizlet 2023

1. Which of the following viruses is most likely to be acquired through casual contact with an infected individual?

Correct answer: A

Rationale: The correct answer is influenza virus. Influenza virus is most likely to be acquired through casual contact with an infected individual as it is transmitted through respiratory droplets. Herpes virus is primarily transmitted by direct contact, such as skin-to-skin contact, making it less likely to be acquired through casual contact. HIV is mainly transmitted through blood and body fluids like semen and vaginal fluids, not through casual contact. Cytomegalovirus (CMV) is an opportunistic infection commonly affecting immunocompromised individuals and is usually transmitted through close personal contact, not casual contact.

2. When a client informs the nurse that he is experiencing hypoglycemia, the nurse provides immediate intervention by providing:

Correct answer: D

Rationale: The correct immediate intervention for hypoglycemia is to provide 10-15 grams of fast-acting simple carbohydrates orally if the client is conscious and able to swallow. This can be achieved by giving 2-3 teaspoons of honey. Honey is a quick source of simple sugars that can rapidly raise blood glucose levels. Commercially prepared glucose tablets or 4-6 ounces of fruit juice are also appropriate options. However, adding sugar to fruit juice is unnecessary as the natural fruit sugar in juice already provides enough simple carbohydrates to raise blood glucose levels. Hard candies are not the best choice for immediate intervention in hypoglycemia as they may not provide a sufficient amount of fast-acting carbohydrates needed to raise blood sugar levels quickly.

3. Which physiologic mechanism best describes the function of the sodium-potassium pump?

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.

4. Which of the following is not a primary function of the kidneys?

Correct answer: D

Rationale: The correct answer is reabsorption of waste products because the kidneys excrete waste products rather than reabsorbing them. Choices A, B, and C are indeed primary functions of the kidneys. The kidneys play a crucial role in regulating blood pressure, activating vitamin D, and producing erythropoietin, which stimulates red blood cell production. Therefore, the primary role of the kidneys is to filter blood, remove waste products, regulate fluid balance, and maintain electrolyte balance.

5. The chemotherapeutic agent 5-fluorouracil (5-FU) is ordered for a client as an adjunct measure to surgery. Which statement about chemotherapy is true?

Correct answer: B

Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers. Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells. Choice C is incorrect as chemotherapy has been proven effective in treating cancer. Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.
