Correct Answer: B

Rationale: The correct location to palpate the dorsalis pedis pulse is lateral to and parallel with the extensor tendon of the big toe. Choices A, C, and D describe the locations for other pulses - popliteal, posterior tibial, and femoral artery respectively. The popliteal pulse is found behind the knee, the posterior tibial pulse is located in the groove between the malleolus and the Achilles tendon, and the femoral artery is situated below the inguinal ligament, halfway between the pubis and the anterior superior iliac spines.

Correct Answer: D

Rationale: The correct answer is the Appendix. Tenderness in the right lower quadrant of the abdomen is a classic sign of appendicitis, which is inflammation of the appendix. The appendix is located in the right lower quadrant. The other choices are incorrect. The spleen is located on the posterolateral wall of the abdominal cavity under the diaphragm. The pancreas is located behind the stomach. The liver fills most of the right upper quadrant and extends to the left midclavicular line.

Correct Answer: D

Rationale: The correct answer is the statement, "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."? This statement would require correction from the nurse because initiating ART when the CD4 count is over 1,000 cells/mm3 is not supported by guidelines. The World Health Organization (WHO) recommends making treatment a priority for those with a CD4 count of ≤350 cells/mm3, as early intervention can help delay disease progression. Therefore, waiting for a CD4 count of over 1,000 cells/mm3 is not in line with current recommendations. Choice A is correct, as studies have shown that using condoms along with ART can significantly reduce the risk of HIV transmission to sexual partners. Choice B is also correct because being Hepatitis C positive does not contraindicate the use of ART. Choice C is correct as well, as ART is typically needed indefinitely to maintain viral suppression and manage HIV. Therefore, the only statement that would require correction is Choice D.

Correct Answer: D

Rationale: To assess the function of cranial nerve XI (spinal accessory nerve), the nurse examines the sternomastoid and trapezius muscles for equal size and strength. The correct method involves asking the client to rotate the head forcibly against resistance to the side of the chin and to shrug the shoulders against resistance from the nurse's hands. Choice A, asking the client to stick out the tongue and watching for tremors, is used to assess cranial nerve XII (hypoglossal nerve). Choice C, depressing the client's tongue with a tongue blade and noting pharyngeal function as the client says 'ah', is the technique for examining cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). Choice B, touching the posterior pharyngeal wall with a tongue blade and noting the gag reflex, is used to evaluate cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve), not cranial nerve XI.

Correct Answer: C

Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.
