1. Which of the following microorganisms are considered normal body flora?

• A. staphylococcus on the skin
• B. streptococcus in the nares
• C. candida albicans in the vagina
• D. pseudomonas in the blood

Correct answer: A

Rationale: Staphylococcus is considered normal body flora as it is commonly found on the skin, being a part of the normal microbiota. While streptococcus in the nares can be part of the normal flora of the upper respiratory tract, it is not as common or as widespread as staphylococcus on the skin. Candida albicans in the vagina is not considered normal flora; it is a common opportunistic pathogen in the vagina. Pseudomonas in the blood is also not considered normal body flora; pseudomonas is not typically found in the blood as part of the normal microbiota.

2. Several passengers aboard an airliner suddenly become weak and suffer breathing difficulty. The diagnosis is likely to be

• A. Outbreak of Asian flu.
• B. Chemical exposure.
• C. Bacterial pneumonia.
• D. Allergic reaction.

Correct answer: B

Rationale: In the scenario described, where multiple passengers on an airliner experience sudden weakness and breathing difficulty simultaneously, the most likely cause is chemical exposure. This is because a sudden onset of similar symptoms in a group of individuals suggests a common environmental factor affecting them. Options A, C, and D are less likely as they do not explain a sudden onset of symptoms in multiple individuals simultaneously. Asian flu (Option A) is a viral infection and would not typically result in sudden symptoms in multiple individuals at the same time. Bacterial pneumonia (Option C) is a localized infection and not a probable cause for a sudden onset of symptoms in a group. An allergic reaction (Option D) would usually occur in individuals with specific allergies rather than affecting a group of passengers at the same time.

3. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

4. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.

5. When caring for clients with Buck’s Traction, the major areas of importance should be:

• A. nutrition, elimination, comfort, safety
• B. ROM exercises, transportation
• C. nutrition, elimination, comfort, safety
• D. elimination, safety, isotonic exercises

Correct answer: C

Rationale: When caring for clients with Buck’s Traction, the major areas of importance should be nutrition, elimination, comfort, and safety. Proper nutrition, including a diet high in protein with adequate fluids, is essential for healing and recovery. Elimination refers to maintaining regular bowel and bladder function. Comfort is crucial to ensure the patient's well-being while in traction, and safety measures should be followed to prevent complications. Choices A, B, and D are incorrect. ROM exercises are not typically a primary concern with Buck’s Traction, making choices A and B incorrect. Isotonic exercises are not specifically related to the care of a client in Buck's Traction, making choice D incorrect.
