Correct Answer: B

Rationale: The correct answer is B: Poor people. Focusing on poor people is likely to cause the most improvement in core measures because individuals living in poverty often face multiple barriers to accessing healthcare and have higher rates of chronic conditions. By targeting this group, the nurse can address social determinants of health, improve healthcare access, and address disparities in healthcare outcomes. Other choices (A, C,
D) are not as impactful as poverty is a significant factor influencing health disparities.

Correct Answer: C

Rationale: The correct answer is C: bacterial endocarditis. Mitral valve stenosis increases the risk of bacterial endocarditis due to turbulent blood flow and potential damage to the heart valve. Prophylactic antibiotics are recommended before certain procedures to prevent bacterial endocarditis in patients with underlying cardiac conditions.


Choice A, hypertension, is incorrect as mitral valve stenosis does not directly increase the risk of developing hypertension.
Choice B, postpartum infection, is not directly related to the risk associated with mitral valve stenosis.
Choice D, upper respiratory infections, is not a specific risk associated with mitral valve stenosis in pregnant patients.

Correct Answer: D

Rationale: The correct answer is D: Graphic record and flow sheet. The nurse will use a graphic record and flow sheet to document the patient's daily weights. This form allows for easy tracking and visualization of weight trends over time. Database (
A) is used for storing large amounts of data but not ideal for daily weight tracking. Progress notes (
B) are for narrative descriptions of patient care, not specific for daily weights. Patient care summary (
C) provides an overview of the patient's care plan, not detailed daily weights.

Correct Answer: C

Rationale: The correct answer is C: Keep the patient's bed linens free of wrinkles. This intervention is important in preventing pressure ulcers, a common complication in patients with impaired skin integrity. Wrinkles in bed linens can create pressure points on the skin, leading to skin breakdown. By keeping the bed linens smooth and wrinkle-free, the patient's skin is protected from excessive pressure, reducing the risk of impaired skin integrity.

A: Maximizing fluid intake is important for overall health but is not directly related to preventing impaired skin integrity.
B: Providing total parenteral nutrition may support the patient's nutritional needs but does not specifically address the risk of impaired skin integrity.
D: Providing snug clothing can increase friction and pressure on the skin, potentially worsening the risk of impaired skin integrity.

Correct Answer: D

Rationale: The correct answer is D: "Don't blow your nose for 2 to 3 weeks." After mastoid surgery, blowing the nose can increase pressure in the surgical area and disrupt healing. Here's the rationale:
1. Blowing the nose can increase pressure in the surgical area and lead to complications.
2. Avoiding blowing the nose helps prevent infection and reduces the risk of damaging the surgical site.
3. It is essential to follow this instruction to promote proper healing and reduce the chances of postoperative complications.
In summary, the other choices are incorrect because inducing a sneeze, exercising, and avoiding side-lying position do not directly relate to the specific care needs after mastoid surgery.
