Correct Answer: D

Rationale: The correct answer is to inform the patient that they will have to lie down on their back during the MRI. This positioning is necessary for the scan to obtain accurate images of the brain.
Choice A is incorrect because the decision on the positioning during the MRI is typically determined by the imaging protocol and not subject to negotiation during the test.
Choice B is incorrect as the reverse Trendelenburg position is not commonly used during MRI scans.
Choice C is incorrect because the radiologist does not usually make decisions on patient positioning during the MRI; it is predetermined by the imaging requirements.

Correct Answer: D

Rationale: Cyclophosphamide (Cytoxan) can cause hemorrhagic cystitis, a condition characterized by inflammation of the bladder wall leading to bleeding.
To prevent this complication, the client should drink at least eight glasses of water a day. Walking to prevent calcium loss (choice
A) and increasing fiber intake (choice
B) are not directly related to the side effects of Cytoxan, making them unnecessary instructions in this case. While nausea is a common side effect of chemotherapy, the immediate reporting of nausea to the doctor (choice
C) is important but not specifically related to the use of Cytoxan in this scenario.

Correct Answer: C

Rationale: The correct answer is '"Her gums look too big for her teeth."?' Hyperplasia of the gums is a known side effect associated with Dilantin therapy. Option A, '"She is very irritable lately,"?' is not a typical side effect of Dilantin. Option B, '"She sleeps quite a bit of the time,"?' is a common side effect of Dilantin but not specific to gum hyperplasia. Option D, '"She has gained about 10 pounds in the last 6 months,"?' is not typically associated with Dilantin therapy and is unrelated to the question.

Correct Answer: A

Rationale: The correct answer is 'a written philosophy.' Structure standards define the conditions needed to operate a system and do not directly involve client care. Examples include philosophy, objectives, goals, hours of operation, and management responsibility.

Choices B, C, and D involve specific procedures and protocols related to client care, which are not structure standards.

Correct Answer: C

Rationale: The correct answer is the kidney(s) because most drugs are excreted in the urine, either as the parent compound or as drug metabolites. The skin is not the primary organ for drug elimination; only a few drugs are excreted in sweat. The lung(s) primarily excrete volatile gases with expiration, not drugs. While the liver metabolizes drugs, it is the kidney(s) that primarily eliminate drugs through urine, especially those with a molecular weight above 300.
