How often must a resident's bed linen be changed?

Correct Answer: D

Rationale: The correct answer is D: Whenever soiled or wet. Bed linens should be changed whenever they are soiled or wet to maintain cleanliness, prevent infections, and ensure comfort for the resident. Changing linens twice a day (A) is excessive and unnecessary unless required for specific medical reasons. Changing linens no more than once a week (B) is insufficient and could lead to hygiene issues. Changing linens only when ordered by the physician (C) may not always align with the resident's immediate needs for cleanliness and comfort.

Correct Answer: C

Rationale: To convert 8 ounces to milliliters, we need to know that 1 ounce is approximately equal to 29.5735 milliliters. Therefore, 8 ounces would be 8 x 29.5735 = 236.588 milliliters. Since we are asked to round to the nearest whole number, 240 mL is the correct answer. Choice A (120 mL) is incorrect as it is half of the correct answer. Choice B (80 mL) is incorrect as it is less than half of the correct answer. Choice D (320 mL) is incorrect as it is close but slightly higher than the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Chronic renal failure. Chronic renal failure is a disorder of the urinary system where the kidneys are unable to effectively filter waste products from the blood. This leads to a buildup of waste products and toxins in the body, causing various symptoms and complications. Rationale: 1. Chronic renal failure specifically refers to the long-term and progressive decline in kidney function, leading to impaired waste filtration. 2. Urinary tract infection (B) is an infection in any part of the urinary system, not a disorder of kidney filtration. 3. Urinary incontinence (C) is the inability to control urination, not related to kidney filtration. 4. End-stage renal disease (D) is the final stage of chronic renal failure where the kidneys have lost most of their function, making it a severe consequence of chronic renal failure, not the disorder itself.

Correct Answer: C

Rationale: The correct answer is C (36 to 48 hours) because the ovum, once released during ovulation, has a lifespan of approximately 24 hours. Sperm can survive in the female reproductive tract for up to 5 days, but if fertilization does not occur within 36 to 48 hours after ovulation, the ovum will degenerate and not be viable for fertilization. Choices A, B, and D are incorrect because they do not align with the known lifespan of the ovum and the window of fertilization opportunity.

Correct Answer: C

Rationale: The correct answer is C: Swelling in the ankles. In congestive heart failure, the heart's inability to pump effectively leads to fluid buildup in the body, causing swelling in the ankles (edema). Decreased urination (A) is a symptom of kidney dysfunction in heart failure. Weight loss (B) is not typical in heart failure due to fluid retention. Decreased pulse (D) is not a common sign of heart failure; in fact, heart failure can lead to a rapid or irregular pulse.
