Correct Answer: B

Rationale: The correct answer is B, weight gain, as it is not typically considered a warning sign of cancer. Changes in bladder and bowel habits (A), indigestion or difficulty in swallowing (C), and a nagging cough or hoarseness (D) are commonly associated with various types of cancer. Weight gain is more commonly linked to factors such as diet, exercise, and hormonal imbalances rather than cancer. It is important to be vigilant about the other warning signs and seek medical attention if any of those symptoms persist.

Correct Answer: C

Rationale: The correct answer is C, the 35-year-old with kidney failure. Patients with kidney failure are at high risk for fluid volume overload due to the kidneys' inability to properly regulate fluid balance. This can lead to accumulation of excess fluids in the body, causing edema, hypertension, and heart failure. In contrast, choices A, B, and D are not at as high risk for fluid volume overload as patients with kidney failure, as their conditions do not directly impact fluid regulation in the body.

Correct Answer: C

Rationale: The normal range for intraocular pressure (IOP) is approximately 10-21 mm Hg. Choice C has an IOP of 11 mm Hg, falling within this normal range, making it the correct answer. Choices A, B, and D are outside the normal range, with A being too low and B and D being too high, indicating abnormal IOP levels. Choice A (8 mm Hg) is below the normal range, while choices B (25 mm Hg) and D (28 mm Hg) are above the normal range, therefore, they are incorrect answers.

Correct Answer: C

Rationale: The correct answer is C: Elevate the head of bed. Elevating the head of the bed helps improve lung expansion and ventilation, making it easier for patients with impaired respiratory function to breathe. This position also helps prevent aspiration and reduces the risk of respiratory complications. Antibiotics (choice A) are not indicated unless specifically prescribed for an infection. Bedrest (choice B) can lead to deconditioning and worsen respiratory function. Suctioning (choice D) every 4 hours is not necessary unless there is excessive secretions present.

Correct Answer: B

Rationale: The correct answer is B because hemoglobin carries oxygen to the tissues, and with a low hemoglobin level of 6 g/dL, there is insufficient oxygen-carrying capacity to meet the body's needs, leading to shortness of breath (SOB). Choice A is incorrect as anemia affects oxygen transport, not absorption. Choice C is incorrect as anemia affects oxygen delivery, not nutrient delivery. Choice D is incorrect as the primary reason for SOB in this scenario is the lack of oxygen-carrying capacity due to low hemoglobin levels, not lung damage from blood loss.
