Nursing Process Practice Questions

Correct Answer: B

Rationale: The correct answer is B: Re-exposure to a specific antigen. Memory cells are formed after initial exposure to an antigen. Upon re-exposure to the same antigen, memory cells quickly recognize and respond, converting into plasma cells to produce antibodies. This process is known as secondary immune response. Incorrect choices: A: An organ transplant - Organ transplant does not involve the conversion of memory cells to plasma cells. C: Release of lymphokines - Lymphokines are signaling molecules secreted by immune cells but do not directly cause memory cells to convert to plasma cells. D: Initial exposure to an antigen - Initial exposure to an antigen leads to the formation of memory cells, not their conversion to plasma cells upon re-exposure.

Correct Answer: D

Rationale: Rationale: - Choice D is correct as it offers the patient autonomy and promotes self-care, which is important for maintaining independence and dignity. - By giving the patient a choice between brushing their own teeth or having assistance, it empowers them to make decisions. - Choices A, B, and C are not as appropriate because they do not address the patient's autonomy and may come across as directive or intrusive, which can further exacerbate the altered thought process.

Correct Answer: C

Rationale: The correct answer is C: fluid volume deficit. In diabetes insipidus, there is an excessive amount of dilute urine excreted, leading to dehydration and fluid volume deficit. The posterior pituitary tumor causes a deficiency in antidiuretic hormone (ADH), which regulates water reabsorption in the kidneys. As a result, the client experiences polyuria and polydipsia, leading to fluid volume deficit. Choices A, B, and D are incorrect because diabetes insipidus does not cause fluid volume excess, incontinence, or diarrhea. The key is to recognize the pathophysiology of diabetes insipidus and its impact on fluid balance.

Correct Answer: D

Rationale: The correct answer is D: high calorie high protein. In COPD exacerbation, the body requires extra calories and protein for energy and muscle strength. High-calorie foods help combat weight loss and fatigue. High-protein foods aid in muscle repair and maintenance. Low-fat low-cholesterol (A) is not ideal as healthy fats are needed. Low-sodium (B) is not necessary unless there is concurrent heart failure. Bland soft diet (C) is not suitable as it does not provide enough calories and protein needed for COPD exacerbation.

Correct Answer: A

Rationale: The correct answer is A: circulating nurse. The circulating nurse is responsible for maintaining cleanliness, ensuring proper temperature, humidity, and lighting in the operating room. They coordinate activities, manage supplies, and ensure a safe environment for the surgical team. The scrub nurse assists the surgeon with instruments and supplies, not environmental conditions. The surgeon's main focus is on performing the surgery, not environmental management. The anesthesiologist is responsible for administering anesthesia and monitoring the patient's vital signs, not the operating room environment.
