A healthcare professional is teaching a client about the use of a metered-dose inhaler (MDI). Which instruction should the professional include?
- A. Inhale for 1 second
- B. Shake the inhaler vigorously
- C. Hold the inhaler 5-7 cm away from the mouth
- D. Hold breath for 5 seconds after inhalation
Correct Answer: B
Rationale: The correct instruction when using a metered-dose inhaler (MDI) is to shake the inhaler vigorously before use. Shaking the inhaler ensures proper mixing of the medication, which is crucial for effective delivery of the medication into the lungs. Inhaling for a specific duration, holding the inhaler at a certain distance from the mouth, or holding the breath after inhalation are not as critical as ensuring proper mixing of the medication by shaking the inhaler.

A nurse is monitoring a client who is receiving continuous enteral feedings. What finding suggests the client is not tolerating the feeding?
- A. Increased bowel sounds
- B. Nausea
- C. Elevated blood pressure
- D. Fever
Correct Answer: B
Rationale: Nausea is a common sign indicating that the client is not tolerating enteral feedings well. It can be a result of various issues such as feeding intolerance, infection, or other underlying conditions. Nausea should be promptly addressed to prevent further complications. Increased bowel sounds (Choice A) are not typically indicative of feeding intolerance. Elevated blood pressure (Choice C) and fever (Choice D) are generally not directly related to enteral feeding intolerance unless there are specific underlying conditions contributing to them.
A nurse is caring for a client who is experiencing fluid volume deficit (FVD). What clinical finding should the nurse expect?
- A. Decreased hematocrit
- B. Increased heart rate
- C. Increased blood pressure
- D. Decreased respiratory rate
Correct Answer: B
Rationale: Increased heart rate is a common sign of fluid volume deficit (FVD) as the body compensates for decreased fluid levels. When a client is experiencing FVD, the body tries to maintain perfusion to vital organs by increasing the heart rate. This compensatory mechanism helps to improve cardiac output and maintain blood pressure. Choices A, C, and D are incorrect because in FVD, hematocrit may be increased due to hemoconcentration, blood pressure tends to decrease as a compensatory response to FVD, and respiratory rate is usually unaffected or may increase due to attempts to maintain oxygenation.
A client with diabetes mellitus is being taught about foot care. What statement by the client indicates an understanding of the teaching?
- A. I will soak my feet in warm water every day
- B. I will wear slippers at all times when out of bed
- C. I will apply lotion between my toes after washing my feet
- D. I will cut my toenails straight across
Correct Answer: B
Rationale: The correct answer is B. Wearing slippers or shoes at all times when out of bed is crucial for clients with diabetes mellitus to protect their feet from injury. Option A is incorrect as soaking feet in warm water can lead to dry skin, making it more susceptible to injuries. Option C is incorrect as applying lotion between the toes can create a moist environment, increasing the risk of fungal infections. Option D is incorrect as cutting toenails straight across is a good practice but is not directly related to preventing foot injuries in clients with diabetes.
A healthcare professional is reviewing a client's medical history and identifies an increased risk for infections. What risk factor should the healthcare professional include?
- A. Frequent handwashing
- B. Increased mobility
- C. High blood pressure
- D. Chronic conditions
Correct Answer: D
Rationale: The correct answer is D: Chronic conditions. Chronic conditions, such as diabetes or immune suppression, can compromise the immune system, making individuals more susceptible to infections. Frequent handwashing (Choice A) is actually a protective measure against infections. Increased mobility (Choice B) and high blood pressure (Choice C) are not directly associated with an increased risk for infections.
A nurse is providing discharge instructions to a client with chronic obstructive pulmonary disease (COPD). What instruction should the nurse include to help improve oxygenation?
- A. Avoid physical activity
- B. Use pursed-lip breathing during activities
- C. Limit sun exposure
- D. Perform weight-bearing exercises
Correct Answer: B
Rationale: The correct answer is B: 'Use pursed-lip breathing during activities.' Pursed-lip breathing improves oxygenation by keeping airways open longer, facilitating better exhalation of carbon dioxide. Choice A is incorrect because avoiding physical activity can lead to deconditioning and worsen oxygenation. Choice C is irrelevant to improving oxygenation in COPD. Choice D is not directly related to improving oxygenation in COPD; weight-bearing exercises are important for bone health but not for oxygenation.
