The nurse is prepping a client for a trip to the operating room. The nurse anticipates that the physician will order which IV fluid?

10% Dextrose

3% NaCl

Lactated Ringer’s

0.45% NaCl

Answer and Explanation

The Correct Answer is C

Choice A reason: 10% Dextrose is a hypertonic solution used for caloric supplementation or hypoglycemia treatment. It can cause hyperglycemia and fluid shifts, making it unsuitable for routine preoperative hydration. Surgical patients need balanced electrolyte solutions to replace fluid losses and maintain homeostasis, which 10% dextrose does not provide effectively.

Choice B reason: 3% NaCl, a hypertonic saline, is used for severe hyponatremia or cerebral edema. It risks causing hypernatremia and fluid overload if not carefully monitored. Preoperative patients typically require isotonic fluids to maintain electrolyte balance and hydration, making 3% NaCl inappropriate for standard surgical preparation.

Choice C reason: Lactated Ringer’s is an isotonic solution containing electrolytes like sodium, potassium, and calcium, closely mimicking plasma. It is ideal for preoperative hydration, as it replaces fluid losses, maintains electrolyte balance, and supports hemodynamic stability during surgery. Its balanced composition makes it the standard choice for surgical patients.

Choice D reason: 0.45% NaCl, a hypotonic solution, is used for maintenance hydration or hypernatremia correction. It provides less sodium than needed for surgical fluid replacement and may cause hyponatremia or fluid shifts. Isotonic fluids like Lactated Ringer’s are preferred preoperatively to ensure electrolyte stability and adequate hydration.

Correct Answer is B

Explanation

Choice A reason: Instructing on walker movement addresses the psychomotor domain, focusing on physical skills. This does not tackle the client’s emotional disengagement or belief of being “too old.” Without addressing motivation, technical instructions may be ineffective, as the client’s psychological barrier prevents engagement, reducing the likelihood of successful learning and adoption.

Choice B reason: Describing quality-of-life benefits targets the affective domain, addressing emotions and attitudes. By emphasizing enhanced independence, safety, and mobility, the nurse can counter the client’s defeatist mindset. This approach fosters motivation, making the client more receptive to learning walker use, as it connects the intervention to personal, meaningful outcomes.

Choice C reason: Explaining walker support for lower extremities focuses on the cognitive domain, providing technical knowledge. While informative, it does not address the client’s emotional disengagement. Without motivating the client by linking the walker to personal benefits, this approach may fail to overcome their resistance, as it lacks an emotional or motivational component.

Choice D reason: Discussing the rationale for walker use targets the cognitive domain, explaining its purpose. While this may enhance understanding, it does not address the client’s emotional barrier or lack of motivation. Without engaging the client’s feelings or highlighting personal benefits, the rationale alone is unlikely to inspire willingness to learn or use the walker.

A. Instruct them to take a long walk an hour before bedtime B. Arrange with laboratory to draw blood outside of sleep hours C. Encourage patients to fall asleep while watching television D. Close the door to patients’ rooms at bedtime E. Provide a warm green tea or coffee with evening meal

Correct Answer is ["B","D"]

Explanation

Choice A reason: A long walk an hour before bedtime may stimulate the body, increasing heart rate and alertness, which can delay sleep onset. Physical activity is beneficial earlier in the day to promote sleep, but close to bedtime, it may disrupt the body’s wind-down process, reducing sleep quality in hospitalized patients.

Choice B reason: Arranging blood draws outside sleep hours minimizes nighttime disruptions, which are critical for restorative sleep. Hospital environments often interrupt sleep with procedures, increasing stress and fatigue. This intervention supports the sleep-wake cycle by ensuring uninterrupted rest, promoting better recovery and reducing physiological stress in patients.

Choice C reason: Watching television before sleep exposes patients to blue light, which suppresses melatonin production, a hormone essential for sleep. This can delay sleep onset and reduce sleep quality. Hospitalized patients need a calm, low-stimulation environment to promote rest, making television an inappropriate intervention for sleep promotion.

Choice D reason: Closing the door at bedtime reduces noise and light from hospital corridors, creating a quieter, darker environment conducive to sleep. This minimizes disruptions, supporting the body’s circadian rhythm and melatonin production. A calm environment is essential for hospitalized patients, who often face sleep challenges due to hospital activity.

Choice E reason: Green tea or coffee contains caffeine, a stimulant that inhibits sleep by blocking adenosine receptors, increasing alertness. Consuming these near bedtime can delay sleep onset and reduce sleep quality. Hospitalized patients require interventions that promote relaxation, not stimulation, making this an inappropriate choice for sleep promotion.
