Correct Answer: A

Rationale: The correct answer is A: Jaundice. Sulfasalazine can cause liver damage as a possible adverse effect, which can manifest as jaundice. Monitoring for jaundice is crucial to detect liver-related adverse effects early. Choices B, C, and D are incorrect. Constipation, oral candidiasis, and sedation are not typically associated with sulfasalazine use. Therefore, the nurse should focus on educating the client specifically about monitoring for jaundice.

Correct Answer: B

Rationale: The correct answer is B: 'Rifampin can turn body fluids orange.' Rifampin is known to cause orange discoloration of body fluids, including urine. This side effect is harmless and does not indicate a need to stop the medication. Choice A is incorrect because stopping isoniazid will not resolve the orange urine discoloration caused by rifampin. Choice C is unnecessary at this point since the orange urine is a known side effect of rifampin and does not require an urgent provider visit. Choice D is incorrect because bladder irritation is not typically associated with isoniazid.

Correct Answer: A

Rationale: Tamoxifen is an antiestrogen medication used primarily in the treatment and prevention of breast cancer. It works by blocking the effects of estrogen in the breast tissue, thereby acting as an antiestrogenic agent. This makes choice A the correct answer. Choice B, antimicrobial, is incorrect as tamoxifen does not possess antimicrobial properties and is not used to treat infections. Choice C, androgenic, is incorrect as tamoxifen has antiestrogenic effects, not androgenic effects. Choice D, anti-inflammatory, is incorrect as tamoxifen's main therapeutic action is antiestrogenic rather than anti-inflammatory.

Correct Answer: A

Rationale: The correct answer is A. Cromolyn sodium is a preventive medication and should not be used as a rescue inhaler when wheezing starts. This indicates a need for further teaching as the parent should understand that cromolyn sodium is not meant for immediate relief of symptoms. Choice B is correct as rinsing the mouth after using the inhaler helps reduce the risk of oral thrush, a common side effect. Choice C is correct as exhaling completely before using the inhaler helps ensure proper inhalation of the medication. Choice D is correct as a spacer can be used if the child has difficulty coordinating breathing with the inhaler, improving medication delivery.

Correct Answer: A

Rationale: The correct answer is A: Reye's syndrome. Aspirin use in children with viral infections has been associated with Reye's syndrome, a serious condition that causes swelling in the liver and brain. Visual disturbances (choice B) are not typically associated with aspirin use in children with viral infections. Diabetes mellitus (choice C) and Wilms' tumor (choice D) are not adverse effects of aspirin use in this context.
