Correct Answer: D

Rationale: The correct answer is D: Cryptorchidism. Cryptorchidism, also known as undescended testicle, is a known risk factor for testicular cancer as the testicle does not descend into the scrotum during fetal development, increasing the risk of cancer development. Testosterone therapy during childhood (A) and early onset of puberty (B) are not directly linked to testicular cancer. Sexually transmitted diseases (C) typically do not increase the risk of testicular cancer. Therefore, choice D is the most relevant risk factor for testicular cancer in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Wear gloves when providing mouth care. This is because standard precautions for AIDS include wearing gloves when in contact with bodily fluids, such as saliva during mouth care. Maintaining strict isolation (A) is not necessary as AIDS is not transmitted through casual contact. Keeping the client in a private room (C) is not required unless the client has an airborne infection. Wearing a gown when delivering food tray (D) is not necessary for standard precautions unless there is a risk of contamination with bodily fluids.

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: 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: A

Rationale: The correct answer is A: Monthly testicular self-examination. This is the best way to detect testicular cancer early because it allows individuals to become familiar with the normal size, shape, and texture of their testicles, making it easier to notice any changes or abnormalities. Self-examination is cost-effective, convenient, and can be done regularly to monitor for any signs of cancer. Annual physician examination (B) may not be frequent enough for early detection. Yearly digital rectal examination (C) is not relevant for detecting testicular cancer. Annual ultrasonography (D) is not recommended as a routine screening tool for testicular cancer.
