The constant noise of a ventilator, monitor alarms, and inf usion pumps predisposes the patient to what form of stress?
- A. Anxiety
- B. Pain
- C. Powerlessness
- D. Sensory overload
Correct Answer: D
Rationale: The correct answer is D: Sensory overload. Constant noise from medical equipment can overwhelm the patient's senses, leading to sensory overload. This can result in increased stress levels, difficulty concentrating, and overall discomfort. Anxiety (A) is related to worry and fear, but in this context, the primary stressor is sensory overload, not anxiety. Pain (B) is a physical sensation, not directly related to the sensory overload caused by noise. Powerlessness (C) refers to a lack of control or influence, which is not the primary form of stress induced by constant noise. Therefore, the correct choice is D as it directly correlates with the impact of the noise on the patient's sensory perception.

The patient’s potassium level is 7.0 mEq/L. Besides dialysis, which of the following actually reduces plasma potassium levels and total body potassium content safely in a patient with renal dysfunction?
- A. Sodium polystyrene sulfonate
- B. Sodium polystyrene sulfonate with sorbitol
- C. Regular insulin
- D. Calcium gluconate
Correct Answer: C
Rationale: Correct Answer: C - Regular insulin
Rationale:
1. Insulin promotes cellular uptake of potassium.
2. When insulin is administered, it moves potassium from extracellular to intracellular space.
3. This decreases plasma potassium levels safely.
4. Other options do not directly lower potassium levels in the same manner.
Summary of Other Choices:
A: Sodium polystyrene sulfonate - exchanges sodium for potassium in the intestines, not reducing total body potassium.
B: Sodium polystyrene sulfonate with sorbitol - similar to A, does not reduce total body potassium.
D: Calcium gluconate - does not directly lower potassium levels, used for treating hyperkalemia-induced cardiac toxicity.
A critically ill patient who is intubated and agitated is restrained with soft wrist restraints. Based on research findings, what is the best nursing action?
- A. Maintain the restraints to protect patient safety.
- B. Remove the restraints periodically to check skin integrity.
- C. Remove the restraints periodically for range of motion.
- D. Assess and intervene for causes of agitation. Answer Key
Correct Answer: D
Rationale: The correct answer is D: Assess and intervene for causes of agitation. In a critically ill patient, agitation while intubated could indicate underlying issues like pain, delirium, or inadequate sedation. By assessing and addressing the root cause of agitation, the nurse can improve patient comfort and prevent potential harm from restraints. Removing restraints periodically for skin integrity (B) and range of motion (C) is important but should not be the primary focus when agitation is present. Maintaining restraints (A) without addressing the agitation could lead to increased distress and potential complications.
represent?
- A. Alveolar oxygen tension.
- B. Oxygen that is chemically combined with hemoglobin .
- C. Oxygen that is physically dissolved in plasma.
- D. Total oxygen consumption.
Correct Answer: B
Rationale: The correct answer is B: Oxygen that is chemically combined with hemoglobin. This is because oxygen primarily travels in the blood by binding to hemoglobin in red blood cells, forming oxyhemoglobin. This process allows for efficient transport of oxygen to tissues throughout the body. Choices A, C, and D are incorrect because:
A: Alveolar oxygen tension refers to the partial pressure of oxygen in the alveoli of the lungs, not the specific form of oxygen in the blood.
C: Oxygen physically dissolved in plasma refers to the small amount of oxygen that is not bound to hemoglobin and is less significant in oxygen transport compared to oxygen bound to hemoglobin.
D: Total oxygen consumption is the overall amount of oxygen utilized by the body, not specifically the form of oxygen bound to hemoglobin for transport.
A 22-year-old patient who experienced a near-drowning accident in a local pool, but now is awake and breathing spontaneously, is admitted for observation. Which assessment will be most important for the nurse to take during the observation period?
- A. Auscultate heart sounds.
- B. Palpate peripheral pulses.
- C. Auscultate breath sounds.
- D. Check pupil reaction to light.
Correct Answer: C
Rationale: The correct answer is C: Auscultate breath sounds. After a near-drowning incident, the main concern is potential respiratory complications such as aspiration pneumonia or pulmonary edema. Auscultating breath sounds will help the nurse assess for any signs of respiratory distress or complications. This assessment is crucial for early detection and intervention.
A: Auscultating heart sounds is important but not as crucial as assessing breath sounds in this scenario.
B: Palpating peripheral pulses is important for circulation assessment but does not address the immediate concern of respiratory complications.
D: Checking pupil reaction to light is more relevant for neurological assessment and not as critical as assessing breathing in this situation.
The nurse is caring for a patient receiving benzodiazepine intermittently. What is the best way to administer such drugs?
- A. Medicate around the clock, rather than as needed, to en sure constant sedation.
- B. Administer the medications through the feeding tube to prevent complications.
- C. Give the highest allowable dose for the greatest effect.
- D. Titrate to a predefined endpoint using a standard sedat ion scale.
Correct Answer: D
Rationale: The correct answer is D: Titrate to a predefined endpoint using a standard sedation scale. This approach ensures individualized dosing based on the patient's response, minimizing the risk of over-sedation or under-treatment. It allows for careful monitoring and adjustment of dosage to achieve the desired level of sedation while avoiding adverse effects.
A: Administering medication around the clock may lead to unnecessary sedation and increased risk of side effects.
B: Administering medications through a feeding tube is not recommended for benzodiazepines as it may affect absorption and increase the risk of complications.
C: Giving the highest allowable dose without considering individual response can result in excessive sedation and adverse effects.
