A nurse is reviewing the medical record for a client who has pneumonia. The nurse should plan to have the client lie on his back with his head lower than his feet to mobilize secretions from which of the following lung segments?
- A. Apical segments
- B. Both upper lobes
- C. Anterior segments of both lower lobes
- D. Posterior segments of both lower lobes
Correct Answer: C
Rationale: Trendelenburg position assists in draining secretions from the anterior lower lung segments.

A nurse in a clinic is reinforcing teaching with a group of clients about preventing low back pain and injury. Which of the following statements should the nurse identify as an indication that the client requires further clarification?
- A. I'll sit with my knees lower than my hips.'
- B. I'll do exercises that strengthen my abdominal muscles.'
- C. I'll wear low-heeled shoes from now on.'
- D. I'll carry heavy objects close to my body.'
Correct Answer: A
Rationale: The correct answer is A: "I'll sit with my knees lower than my hips." This statement indicates a misunderstanding as it can actually contribute to low back pain. Sitting with knees lower than hips can increase pressure on the lower back. The correct sitting posture to prevent low back pain is to have knees at or slightly above hip level. This helps maintain the natural curve of the spine.
Explanation for other choices:
B: "I'll do exercises that strengthen my abdominal muscles." - Correct, as strong core muscles can help support the lower back.
C: "I'll wear low-heeled shoes from now on." - Correct, as high heels can alter posture and contribute to back pain.
D: "I'll carry heavy objects close to my body." - Correct, as this reduces strain on the back when lifting.
A nurse is assisting in preparing a presentation at a senior center about age-related musculoskeletal changes. Which of the following alterations is appropriate for the nurse to include?
- A. Decreased muscle mass
- B. Thickened vertebral disks
- C. Decreased chest width
- D. Increased force of isometric contractions
Correct Answer: A
Rationale: The correct answer is A: Decreased muscle mass. As individuals age, there is a natural decline in muscle mass known as sarcopenia. This is due to a decrease in muscle fiber size and number. The nurse should include this alteration in the presentation because it is a common age-related musculoskeletal change that can lead to weakness, decreased mobility, and increased risk of falls in older adults.
Choices B, C, and D are incorrect because thickened vertebral disks, decreased chest width, and increased force of isometric contractions are not typical age-related musculoskeletal changes. Thickened vertebral disks are more associated with degenerative disc disease, decreased chest width is not a common age-related change, and increased force of isometric contractions is not a typical alteration seen in older adults.
When a nurse obtains an unusually low blood pressure measurement for a client whose blood pressure is generally elevated, she considers the possibility of a problem with her technique. Which of the following sources of error should she consider as a possible cause of the low reading?
- A. Wrapping the cuff too loosely around the client's arm
- B. Positioning the client's arm above heart level
- C. Measuring blood pressure right after the client's mealtime
- D. Deflating the cuff too slowly
Correct Answer: B
Rationale: The correct answer is B: Positioning the client's arm above heart level. When the client's arm is positioned above heart level, it can lead to an artificially low blood pressure reading due to gravitational effects. This position can cause blood to pool in the arm, reducing the pressure in the arteries and resulting in an inaccurate measurement. This error is known as hydrostatic pressure error. Wrapping the cuff too loosely (choice A) can lead to an inaccurate reading due to inadequate compression of the artery. Measuring blood pressure right after a meal (choice C) can also affect the reading due to the body's response to food intake. Deflating the cuff too slowly (choice D) can result in a falsely elevated diastolic reading.
A nurse is caring for a client who has type I diabetes mellitus and is not adhering to guidelines for therapy. Which of the following factors should the nurse consider as contributing to the nonadherence?
- A. Gender
- B. Culture
- C. Allergies
- D. Dexterity
- E. Motivation
Correct Answer: B,D,E
Rationale: Cultural beliefs, dexterity limitations, and motivation significantly impact adherence to diabetes management.
A nurse is reinforcing teaching with a client on how to use meditation and progressive relaxation techniques to manage stress. Which of the following physiologic outcomes should the nurse instruct the client to expect?
- A. Arousal reduction
- B. Decreased blood pressure
- C. Decreased heart rate
- D. Increased oxygen consumption
- E. Increased respiratory rate
Correct Answer: A,B,C
Rationale: Meditation and relaxation techniques reduce physiological stress responses, leading to lower blood pressure, heart rate, and arousal.
