A client is receiving oxygen at 4 L per nasal cannula. What comfort measure may the nurse delegate to assistive personnel (AP)?

  • A. Apply water-soluble ointment to nares and lips.
  • B. Periodically turn the oxygen down or off.
  • C. Replaces the oxygen tubing with a different type.
  • D. Turn the client every 2 hours or as needed.
Correct Answer: A

Rationale: The correct answer is A because applying water-soluble ointment to nares and lips helps prevent skin breakdown and discomfort caused by the oxygen flow. This task is within the scope of practice for assistive personnel (AP) as it does not require specialized medical knowledge or training.

Choice B is incorrect because adjusting oxygen flow should only be done by licensed healthcare providers based on the client's prescribed oxygen therapy. Choice C is incorrect as replacing oxygen tubing requires knowledge of oxygen delivery systems and potential risks associated with incorrect tubing selection. Choice D is incorrect because turning the client every 2 hours is a nursing intervention related to preventing pressure ulcers, not specifically related to oxygen therapy comfort measures.

A client who is found unresponsive has the following arterial blood gases: pH 7.12,
PCO2 90, and HCO3 26. The nurse interprets the results as indicating which
condition?

  • A. Metabolic acidosis with partial compensation
  • B. Respiratory acidosis with partial compensation
  • C. Metabolic acidosis without compensation
  • D. Respiratory acidosis without compensation
Correct Answer: D

Rationale: The correct answer is D, respiratory acidosis without compensation. The low pH and high PCO2 levels indicate respiratory acidosis. HCO3 is within normal range, suggesting no metabolic compensation. This is not metabolic acidosis as the HCO3 level is not elevated. Not partial compensation as the HCO3 level is not compensating for the respiratory acidosis.

Which of the following nursing activities is most important when a client comes back from a respiratory test if they have respiratory problems?

  • A. Allow the client to rest
  • B. Assess the client’s airway
  • C. Teach the client important information
  • D. Teach the family about respiratory disease
Correct Answer: B

Rationale: The correct answer is B. Assessing the airway is critical immediately after a respiratory test, especially if the client has pre-existing respiratory issues. A (rest) is secondary until stability is confirmed. C and D involve education, which is important but not urgent compared to ensuring airway patency.

Following an asthmatic attack, a mother asks the physician how to prevent another asthmatic attack. The physician should:

  • A. Tell her that asthmatic attacks cannot be prevented.
  • B. Help the mother identify triggers that cause asthmatic attacks and show her how to avoid them.
  • C. Change her medication.
  • D. Immediately move her family to a dry climate.
Correct Answer: B

Rationale: The correct answer is B. Identifying and avoiding triggers is key to preventing asthma attacks. A is incorrect because prevention is possible. C (changing medication) may help but is secondary. D (moving to a dry climate) is impractical and unnecessary.

A male adult patient on mechanical ventilation is receiving pancuronium bromide (Pavulon), 0.01 mg/kg I.V. as needed. Which assessment finding indicates that the patient needs another pancuronium dose?

  • A. Leg movement
  • B. Finger movement
  • C. Lip movement
  • D. Fighting the ventilator
Correct Answer: D

Rationale: The correct answer is D: Fighting the ventilator. This indicates inadequate muscle relaxation, requiring another dose of pancuronium. Leg, finger, and lip movements are not reliable indicators of muscle relaxation in a mechanically ventilated patient. Fighting the ventilator suggests the patient is not adequately sedated or paralyzed, requiring further intervention to maintain optimal ventilation and oxygenation.

When instructing the client with chronic stable angina it should be emphasized that angina may be brought on by many precipitating factors including the following:

  • A. Rest
  • B. Sudden change in position
  • C. Severe depression
  • D. Consumption of a heavy meal
Correct Answer: D

Rationale: Step 1: Consumption of a heavy meal can lead to increased blood flow to the digestive system, causing a temporary reduction in blood flow to the heart muscle.
Step 2: This reduction can trigger angina symptoms in individuals with chronic stable angina.
Step 3: Emphasizing this to the client helps in understanding potential triggers to manage their condition effectively.
Step 4: Rest (A) is usually recommended to relieve angina, sudden change in position (B) is not a common trigger, and severe depression (C) can exacerbate angina but is not a direct precipitating factor like heavy meals.
