1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. Which of the following conditions increases a client's risk of aspiration of stomach contents?

• A. A client is in restraints
• B. A client has a scaphoid abdomen
• C. A client is lying prone
• D. More than one answer is correct

Correct answer: A

Rationale: A client in restraints is at an increased risk of aspiration of stomach contents. When a client is restrained, they may be unable to effectively move or turn their body if they begin to vomit, which can lead to aspiration. This lack of mobility can hinder their ability to protect their airway. On the other hand, a scaphoid abdomen, which is sunken or hollowed, is not a direct risk factor for aspiration. Additionally, lying prone, facing downward, does not necessarily increase the risk of aspiration, as aspiration is more likely when lying supine (facing upward). Therefore, the correct answer is that a client is in restraints.

3. The nurse teaches a patient about the transmission of pulmonary tuberculosis (TB). Which statement, if made by the patient, indicates that teaching was effective?

• A. I will avoid being outdoors whenever possible.
• B. My husband will be sleeping in the guest bedroom.
• C. I will take the bus instead of driving to visit my friends.
• D. I will keep the windows closed at home to contain the germs.

Correct answer: B

Rationale: To prevent the transmission of pulmonary tuberculosis, it is important for the infected individual to minimize exposure to close contacts and household members. Sleeping alone in a separate room, like the guest bedroom, is an effective measure. The other choices are not ideal: Choice A is incorrect because spending time outdoors is encouraged for ventilation; Choice C is incorrect as using public transportation increases the risk of transmission; Choice D is incorrect because keeping windows closed limits ventilation, which is necessary to reduce the concentration of infectious particles in the air.

4. A complication of osteoporosis is _______________?

• A. rheumatoid arthritis
• B. gouty arthritis
• C. dorsiflexion
• D. joint deformity

Correct answer: D

Rationale: Joint deformity is a well-known complication of osteoporosis, leading to structural changes in the joints due to bone loss and fragility. Gouty arthritis and rheumatoid arthritis are distinct types of arthritis that are not direct complications of osteoporosis. Dorsiflexion is a movement related to the foot's range of motion and is not a typical complication of osteoporosis.

5. Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?

• A. The test determines if the client is anemic and needs iron supplements
• B. The test determines if there is excess glucose building up in the urine
• C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
• D. The test determines the amount of hemoglobin that is coated with glucose

Correct answer: D

Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.
