1. When planning care for a client on mechanical ventilation, which mode of ventilation that increases the effort of the client's respiratory muscles should NOT be included in the plan of care?

A. Assist-control
B. Synchronized intermittent mandatory ventilation
C. Continuous positive airway pressure
D. Pressure support ventilation

Correct answer: Assist-control

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.

2. How many ounces are in 1 cup?

A. 8
B. 80
C. 800
D. 8000

Correct answer: A

Rationale: 1 cup is equivalent to 8 ounces. This conversion is commonly used in cooking and baking recipes, where precise measurements are crucial for the successful outcome of dishes. Knowing this conversion helps ensure that ingredients are accurately measured and the recipe turns out as intended. Choices B, C, and D are incorrect because they do not reflect the correct conversion between cups and ounces. 80, 800, and 8000 ounces are significantly higher quantities than what is found in 1 cup, which is 8 ounces.

3. A client is being instructed on the use of an incentive spirometer. Which of the following statements by the client indicates an understanding of the teaching?

A. ''I will place the adapter on my finger to read my blood oxygen saturation level.''
B. ''I will lie on my back with my knees bent.''
C. ''I will rest my hand over my abdomen to create resistance.''
D. ''I will take in a deep breath and hold it before exhaling.''

Correct answer: ''I will take in a deep breath and hold it before exhaling.''

Rationale: The correct answer demonstrates an understanding of the proper technique for using an incentive spirometer. Incentive spirometry helps to improve lung function by encouraging deep breathing and sustaining the inhalation to fully expand the lungs. Options A, B, and C are incorrect because they do not reflect the correct instructions for using an incentive spirometer.

4. Which of the following procedures always requires surgical asepsis?

A. Vaginal instillation of conjugated estrogen
B. Urinary catheterization
C. Nasogastric tube insertion
D. Colostomy irrigation

Correct answer: B

Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity. Vaginal instillation of conjugated estrogen, nasogastric tube insertion, and colostomy irrigation do not always require surgical asepsis as they involve different levels of sterility and infection control measures.

5. What is the primary goal of performing a bed bath?

A. To cleanse, refresh, and provide comfort to the client who must remain in bed
B. To expose the necessary parts of the body
C. To develop skills in bed bath
D. To check the body temperature of the client in bed

Correct answer: A

Rationale: The primary goal of performing a bed bath is to cleanse, refresh, and provide comfort to clients who are unable to leave their bed. This helps maintain their hygiene, promotes skin health, and enhances their overall well-being. Choice B is incorrect as the primary purpose is not to expose body parts but to provide hygiene and comfort. Choice C is incorrect as the main goal is client care, not skill development. Choice D is incorrect as checking body temperature is not the main purpose of a bed bath.
