Correct Answer: B

Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.

Correct Answer: A

Rationale: For an 82-year-old female client with type 2 diabetes and degenerative arthritis, the nurse should recommend seeking routine nail care with a podiatrist. This is crucial to ensure proper and safe toenail care, reducing the risk of injury and infection, which is especially important for diabetic clients. Encouraging monthly pedicures at a nail salon (choice B) may not address the underlying issues related to diabetes and arthritis. Soaking feet for 10 minutes before cutting nails (choice C) may help soften the nails but does not address the difficulty the client faces in cutting them. Asking a family member to cut toenails (choice D) may not guarantee the expertise needed for proper diabetic foot care, which a podiatrist can provide.

Correct Answer: B

Rationale: Chest pain unrelieved after taking 3 sequential nitroglycerin tablets indicates a possible myocardial infarction and requires immediate medical attention.

Correct Answer: C

Rationale: The correct answer is C: Hemoglobin and hematocrit. Epoetin alfa is a medication that stimulates red blood cell production, so monitoring hemoglobin and hematocrit levels is essential to assess its effectiveness. These values reflect the oxygen-carrying capacity of the blood and can indicate if the treatment is improving anemia related to chronic kidney disease. Choices A, B, and D are incorrect. Blood urea nitrogen (BUN) and serum creatinine are indicators of kidney function, while serum potassium levels are monitored due to electrolyte imbalances commonly seen in kidney disease, but they do not directly reflect the effectiveness of epoetin alfa.

Correct Answer: C

Rationale: The correct answer is to decrease IV fluids to the keep vein open (KVO) rate. The client is showing signs of fluid volume excess, such as drowsiness, headache, elevated CVP, crackles, bounding pulses, and increased blood pressure. Decreasing the IV fluids will help prevent further fluid overload. Reviewing the last administration of IV pain medication (Choice A) may be necessary but addressing the fluid balance issue is the priority. Administering a PRN dose of acetaminophen (Choice B) may help with the headache but does not address the underlying fluid overload. Calculating total intake and output (Choice D) is important but does not directly address the immediate issue of fluid overload and its associated symptoms.
