1. Which of the following is a local sign of infection?

• A. Swelling
• B. Rapid pulse
• C. Fever
• D. High white blood count

Correct answer: A

Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.

2. Albert B. is incontinent of urine. He also wears glasses and hearing aids. His ____________lead(s) to his risk for falls.

• A. incontinence and loss of vision
• B. loss of vision
• C. incontinence
• D. loss of hearing

Correct answer: B

Rationale: Albert B. is at risk for falls due to two factors: his incontinence and his loss of vision. Loss of vision significantly impairs one's ability to navigate and avoid obstacles, thereby increasing the risk of falls. While incontinence is a risk factor for falls, the primary concern in this case is the loss of vision since it directly affects balance and safety. Therefore, the correct answer is 'loss of vision.' Choices A, C, and D are incorrect because they do not address the key factor of impaired vision leading to the risk of falls.

3. Which of the following situations might warrant a laboratory magnesium level?

• A. Hyperthyroidism
• B. Arthritis
• C. Ulcerative colitis
• D. Depression

Correct answer: C

Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.

4. 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.

5. Mobility is an important human function. The hazards of immobility lead to many physical and emotional problems. Immobility can lead to detrimental cardiac, muscular, respiratory, skeletal, urinary, gastrointestinal, skin, and emotional changes. Which of the following is an example of a skeletal hazard of immobility?

• A. Contractures.
• B. Constipation.
• C. Calcium loss.
• D. Catabolism.

Correct answer: C

Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.
