1. A child's thymus gland is fully formed and proportionately larger than an adult's. Which of the following processes that contribute to immunity takes place in the thymus gland?

• A. Differentiation of B cells
• B. Production of natural killer (NK) cells
• C. Proliferation of T cells
• D. Filtration of antigens from the blood

Correct answer: C

Rationale: The correct answer is C: Proliferation of T cells. The thymus gland is responsible for the maturation and proliferation of T cells, which play a crucial role in adaptive immunity. Option A, differentiation of B cells, is incorrect because B cell maturation primarily occurs in the bone marrow. Option B, production of natural killer (NK) cells, is incorrect as NK cells are mainly produced in the bone marrow and lymph nodes. Option D, filtration of antigens from the blood, is incorrect as antigen filtration is not a primary function of the thymus gland.

2. What is the common denominator of all forms of heart failure?

• A. Pulmonary edema
• B. Jugular venous distention
• C. Peripheral edema
• D. Reduced cardiac output

Correct answer: D

Rationale: The correct answer is D: Reduced cardiac output. All forms of heart failure share the common denominator of reduced cardiac output, which leads to inadequate tissue perfusion. Pulmonary edema (choice A) is a consequence of heart failure but not the common denominator. Jugular venous distention (choice B) and peripheral edema (choice C) are signs of heart failure but do not represent the common denominator shared by all forms.

3. A patient is prescribed medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse teach the patient about the proper use of this medication?

• A. Take the medication at the same time each day to maintain consistent hormone levels.
• B. Avoid prolonged sun exposure while taking this medication.
• C. Discontinue the medication if side effects occur.
• D. Apply the medication once a week.

Correct answer: A

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Consistency in timing helps regulate the hormone levels in the body, ensuring the medication's optimal benefit. Choice B is incorrect as there is no specific need to avoid sun exposure with this medication. Choice C is incorrect because discontinuing the medication without consulting the healthcare provider may not be safe. Choice D is incorrect as medroxyprogesterone acetate is typically taken orally and not applied topically once a week.

4. An older adult patient has just sheared the skin on her elbow while attempting to boost herself up in bed, an event that has precipitated acute inflammation in the region surrounding the wound. Which of the following events will occur during the vascular stage of the patient's inflammation?

• A. Outpouring of exudate into interstitial spaces
• B. Chemotaxis
• C. Accumulation of leukocytes along epithelium
• D. Phagocytosis of cellular debris

Correct answer: A

Rationale: During the vascular stage of inflammation, there is an outpouring of exudate into the interstitial spaces, leading to swelling and edema. Choice B, chemotaxis, occurs during the cellular stage of inflammation, where leukocytes move to the site of injury in response to chemical signals. Choice C, accumulation of leukocytes along the epithelium, is not a typical event during the vascular stage. Phagocytosis of cellular debris, as in choice D, mainly occurs during the resolution stage of inflammation.

5. When a healthcare professional observes muscle stiffening occurring within 6 to 14 hours after death, the healthcare professional should document this finding as _____ present.

• A. Livor mortis
• B. Gangrene
• C. Algor mortis
• D. Rigor mortis

Correct answer: D

Rationale: The correct answer is D, Rigor mortis. Rigor mortis is the stiffening of muscles after death, typically beginning within 6 to 14 hours. Livor mortis (choice A) refers to the pooling of blood in the lowest tissues causing discoloration, gangrene (choice B) is the death of body tissue due to lack of blood flow, and algor mortis (choice C) is the cooling of the body after death.
