1. A client who is receiving mechanical ventilation and has an ideal weight of 60 kg should have the tidal volume set at which of the following?
- A. 300 mL
- B. 480 mL
- C. 800 mL
- D. 950 mL
Correct answer: B
Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.
2. A client is unconscious with a breathing pattern characterized by alternating periods of hyperventilation and apnea. The nurse should document that the client has which of the following respiratory alterations?
- A. Kussmaul respirations
- B. Apneustic respirations
- C. Cheyne-Stokes respirations
- D. Stridor
Correct answer: C
Rationale: Cheyne-Stokes respirations are characterized by periods of deep, rapid breathing followed by periods of apnea. This pattern is often seen in clients with neurological or cardiac conditions. Kussmaul respirations are deep and rapid breaths often associated with metabolic acidosis. Apneustic respirations are characterized by prolonged inhalations with shortened exhalations and can indicate damage to the pons. Stridor is a high-pitched, noisy respiratory sound usually associated with upper airway obstruction. Therefore, in this scenario, the client's alternating pattern of hyperventilation and apnea aligns with Cheyne-Stokes respirations.
3. A client with asthma presents with bilateral wheezing, decreased pulse oxygen saturation, and suprasternal retraction on inhalation. Which actions should the nurse take? (SATA)
- A. Administer prescribed salmeterol (Serevent) inhaler.
- B. Assess the client for a tracheal deviation.
- C. Administer oxygen to maintain saturations above 94%.
- D. Perform peak expiratory flow measurements.
Correct answer: C
Rationale: Suprasternal retraction during inhalation suggests the client is using accessory muscles due to difficulty in moving air into the respiratory passages caused by airway narrowing. The presence of bilateral wheezing and decreased pulse oxygen saturation further support airway narrowing. In this situation, immediate intervention is necessary to improve oxygenation. Administering oxygen to maintain saturations above 94% is crucial to support oxygenation. While administering a rescue inhaler may be warranted, the priority in this scenario is ensuring adequate oxygenation to address the respiratory distress.
4. A client with asthma has developed viral pharyngitis. Which of the following findings should the nurse expect?
- A. Petechiae on the chest and abdomen
- B. WBC 16,000/mm3
- C. Negative throat culture
- D. Severe hyperemia of pharyngeal mucosa
Correct answer: C
Rationale: Viral pharyngitis is typically caused by a virus, not bacteria, so a negative throat culture is an expected finding. The presence of petechiae on the chest and abdomen (Choice A) is not a common manifestation of viral pharyngitis. Elevated WBC count (Choice B) is more indicative of a bacterial infection rather than a viral one. Severe hyperemia of the pharyngeal mucosa (Choice D) is a possible finding in pharyngitis but is not specific to viral pharyngitis.
5. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which assessment finding requires the nurse to take immediate action?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 22 breaths per minute
- C. Client reports shortness of breath
- D. Client's respiratory rate decreases to 10 breaths per minute
Correct answer: D
Rationale: A decrease in the client's respiratory rate to 10 breaths per minute, while receiving oxygen therapy for COPD, is a concerning finding that may indicate carbon dioxide retention and respiratory depression. This situation requires immediate action to prevent further complications. An oxygen saturation of 90% is within an acceptable range for COPD patients on oxygen therapy. A respiratory rate of 22 breaths per minute and reports of shortness of breath are common in clients with COPD and may not necessitate immediate action unless accompanied by other concerning symptoms.
