Correct Answer: B

Rationale: Fludrocortisone replacement in Addison's disease involves mimicking the action of aldosterone, a mineralocorticoid that causes the retention of sodium and water. Excessive retention of sodium and water can lead to weight gain. Therefore, a sudden increase in weight, especially a significant amount like 6 pounds in one week, can indicate an overdose of fludrocortisone. Choices A, C, and D are incorrect because oily skin and hair, loss of muscle mass, and increased blood glucose levels are not typically associated with excessive fludrocortisone replacement.

Correct Answer: D

Rationale: The correct answer is the right lower quadrant. The nurse starts auscultating in this quadrant at the ileocecal valve as bowel sounds are normally always present there. Then, the nurse proceeds to listen for bowel sounds in the other quadrants. Choices A, B, and C are incorrect as the initial placement of the stethoscope should be in the right lower quadrant to assess bowel sounds post-surgery.

Correct Answer: A

Rationale: Explanation: Parents should be taught that putting alcohol or other antimicrobials on the cord is no longer recommended for cord care. This can interfere with the natural healing process and may increase the risk of irritation or infection. Washing hands before and after providing cord care is essential to prevent the transfer of pathogens. Placing the baby's diaper below the cord allows it to be exposed to air and promotes drying, reducing the risk of infection. It is normal for the cord to turn dark as it dries, so calling the physician only if the cord becomes red, swollen, or has discharge is appropriate. Therefore, the statement '"I should put alcohol on my baby's cord 3-4 times a day."?' indicates a need for further teaching about cord care.

Correct Answer: B

Rationale: The nurse should immediately obtain a Doppler device and recheck the pulses. The dorsalis pedis and posterior tibial pulses can be difficult to assess and might need to be verified with a Doppler device. Since the client just had surgery with a risk of arterial insufficiency, close monitoring is crucial. If pulses are not palpable, it indicates an emergent situation requiring immediate physician notification. Waiting 30 minutes before reassessment could lead to foot ischemia. While documenting findings is essential, it should follow pulse confirmation or necessary interventions to ensure the client's foot viability.

Correct Answer: D

Rationale: The correct answer is Fluoxetine. Among the options provided, Fluoxetine is the medication least likely to cause tinnitus. Gentamicin, Lasix, and Aspirin are known ototoxic medications that have a potential side effect of causing tinnitus, a ringing in the ear. Gentamicin is an antibiotic, Lasix is a diuretic, and Aspirin is a common pain reliever that can lead to tinnitus. In contrast, Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) primarily used as an antidepressant, and it has a lower risk of causing tinnitus compared to the other options.
