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: A

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. 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.

3. A client is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

A. Dehydration is treated with calcium supplements.
B. Dehydration can increase the risk of preterm labor.
C. Dehydration is associated with gastroesophageal reflux.
D. Dehydration is caused by decreased hemoglobin and hematocrit.

Correct answer: B

Rationale: Dehydration can lead to an imbalance in electrolytes and cause uterine irritability, potentially leading to preterm contractions. It is essential for the nurse to educate the client on the importance of adequate hydration to reduce the risk of preterm labor. The statement 'Dehydration can increase the risk of preterm labor' directly addresses the client's condition and provides relevant information for their understanding and management of the situation.

4. Which term is best described as a systematic, rational method of planning and providing nursing care for individuals, families, groups, and communities?

A. Assessment
B. Nursing Process
C. Diagnosis
D. Implementation

Correct answer: B

Rationale: The correct answer is B: Nursing Process. The nursing process is a systematic, rational method that guides nurses in planning and delivering patient care. It involves a series of steps including assessment, diagnosis, planning, implementation, and evaluation. By utilizing the nursing process, nurses can provide individualized care tailored to the specific needs of patients, families, groups, and communities. Choice A, Assessment, is a step within the nursing process but does not encompass the entire process itself. Choice C, Diagnosis, is another step within the nursing process and focuses on identifying the patient's health problems. Choice D, Implementation, is also a step in the nursing process where the care plan is put into action, but it does not solely describe the entire systematic and rational method of planning and providing nursing care.
