Correct Answer: B

Rationale: The correct answer is B - Avoid traumatic injuries and exposure to any infection. For a client with pancytopenia caused by chemotherapy, their immune system is compromised, making them more susceptible to infections and bleeding. By avoiding traumatic injuries and exposure to infections, the client can reduce the risk of complications. Option A is incorrect because aggressive mouth care may further damage the already compromised oral mucosa. Option C is incorrect because excessive fluid intake may not be necessary and could worsen electrolyte imbalances. Option D is incorrect because muscle cramps and tingling sensations are not directly related to the main concern of infection and bleeding in pancytopenia.

Correct Answer: C

Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to directly gather data from the patient's body, such as vital signs, appearance, and overall health status. It provides essential information to establish a patient's database, including baseline values and potential health issues. Reviewing current literature (A) helps in decision-making but does not directly establish a patient's database. Checking orders for tests (B) and ordering medications (D) are part of the treatment process and do not focus on gathering initial patient data.

Correct Answer: B

This statement shows an understanding of reducing HIV transmission by promoting harm reduction strategies like needle exchange programs, which help prevent sharing of contaminated needles. This approach is evidence-based and effective in reducing the spread of HIV among injection drug users. Choice A is incorrect because breastfeeding by HIV-positive mothers can transmit the virus to infants. Choice C is incorrect as birth control pills do not protect against HIV, only against pregnancy. Choice D is incorrect as natural skin condoms do not provide the same level of protection against HIV as latex condoms do.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Involvement of the sacral plexus can affect bladder control, leading to bladder problems. It can also impact bowel function, requiring bowel management. Additionally, the sacral plexus plays a role in sexual function, so assessment should include sexual activity. Therefore, all options are relevant when assessing a disease process involving the sacral plexus. Other choices are incorrect as they do not cover the comprehensive assessment needed for this specific condition.

Correct Answer: A

Rationale: The correct answer is A because sharp pain is a subjective cue as it is based on the client's personal experience and perception. The client is the only one who can report the presence and intensity of pain. B: Small bloody drainage is an objective cue that can be observed and measured by the nurse. C: Temperature of 102 degrees F is an objective cue that can be measured using a thermometer. D: Pulse rate of 90 beats per minute is an objective cue that can be measured using a pulse oximeter. In summary, subjective cues are based on the client's feelings and perceptions, while objective cues are observable and measurable by the healthcare provider.
