Correct Answer: A

Rationale: The correct answer is A: To prevent Rh sensitization in future pregnancies. RhoGAM is given to an Rh-negative mother to prevent the development of antibodies against Rh-positive blood cells. This prevents Rh sensitization, which could lead to hemolytic disease in future Rh-positive pregnancies. Choices B, C, and D are incorrect because RhoGAM is not used to treat anemia in the newborn, increase the mother's white blood cell count, or prevent infection in the newborn.

Correct Answer: B

Rationale: The correct answer is B. When using standard precautions, healthcare providers should wear clean exam gloves to perform perineal catheter care. This approach helps prevent the transmission of pathogens and ensures the safety of both the client and the healthcare provider. Choice A is incorrect because applying sterile gloves for a finger stick blood sample is unnecessary when non-sterile gloves would suffice. Choice C is incorrect because replacing the needle cap after giving an intramuscular injection is not directly related to standard precautions. Choice D is incorrect because wearing a paper gown is not a standard precaution for preventing the transmission of droplet pathogens.

Correct Answer: A

Rationale: The correct answer is to recommend increasing the intake of dried peaches and apricots. A serum potassium level of 3.0 mEq/L is considered low. Increasing the intake of potassium-rich foods can help raise the serum potassium level, preventing complications such as muscle weakness and cardiac arrhythmias. Choice B, reducing intake of red meats, is incorrect because red meats are not specifically related to potassium levels. Choice C, encouraging the use of a soft toothbrush, is unrelated to addressing low potassium levels. Choice D, forcing fluid intake to 1500 mL daily, is not the appropriate intervention for low serum potassium; instead, increasing potassium-rich foods is more beneficial.

Correct Answer: B

Rationale: A tea party in the courtyard provides a social and physical activity suitable for wheelchair-bound older residents who are mentally alert. It offers an opportunity for social interaction, enjoyment of the outdoors, and participation in a physical activity without the need for extensive mobility. An open-air concert may not provide the same level of social interaction or physical engagement as a tea party. A team ring-toss competition may be physically challenging for wheelchair-bound residents. A picnic in the park could present challenges related to accessibility and might not foster the same level of social interaction as a tea party in a more contained courtyard setting.

Correct Answer: D

Rationale: To maintain sterility when preparing a sterile field, it is essential to avoid reaching over the sterile field. This action can introduce contaminants from the nurse's clothing or unsterile areas, compromising the sterility of the field. Placing sterile items around the sterile field (choice A) is incorrect as it may increase the risk of contamination by extending the area where non-sterile items may come in contact. Keeping hands below waist level (choice B) is also incorrect as it does not prevent contamination effectively. Opening the sterile package away from the body (choice C) is incorrect since it exposes the contents to the nurse's body, which is not sterile.
