A nurse is caring for a client who is experiencing an acute asthma attack. Which of the following should the nurse identify as a contributing factor to the client's manifestations?
- A. Suppressed bronchiolar inflammatory response
- B. Decreased responsiveness of airways to allergens
- C. Acute loss of alveolar elasticity
- D. Inability to exhale retained carbon dioxide
Correct Answer: D
Rationale: The correct answer is D: Inability to exhale retained carbon dioxide. During an acute asthma attack, there is airway obstruction, leading to air trapping and difficulty exhaling. This causes retention of carbon dioxide, leading to respiratory acidosis. This acidosis can further worsen the bronchoconstriction and airway inflammation in asthma. Choices A, B, and C do not directly contribute to the manifestations of an acute asthma attack. Suppressed bronchiolar inflammatory response (A) and decreased responsiveness of airways to allergens (B) would not cause the acute symptoms seen in an asthma attack. Acute loss of alveolar elasticity (C) is not a primary contributing factor to the acute manifestations of asthma.

A nurse is assessing a client who has a pressure injury. Which of the following findings should the nurse expect as an indication the wound is healing?
- A. Wound tissue firm to palpation
- B. Dry brown eschar
- C. Light yellow exudate
- D. Dark red granulation tissue
Correct Answer: D
Rationale: The correct answer is D: Dark red granulation tissue. Granulation tissue is a sign of healing in a wound, indicating new blood vessels and collagen formation. Dark red color indicates good blood supply. A: Firm wound tissue can indicate infection or inadequate healing. B: Dry brown eschar is a sign of necrotic tissue, not healing. C: Light yellow exudate can indicate infection or inflammation.
A nurse is caring for a client who is receiving a 0.9% sodium chloride via IV infusion. The client has become dyspneic with a blood pressure of 140/100 mm Hg, a fluid intake of 960 mL, and an output of 300 mL in the past 12 hr. Which of the following actions should the nurse take?
- A. Lower the head of the bed to semi-Fowler's.
- B. Administer prescribed corticosteroids.
- C. Slow infusion rate and contact the provider.
- D. Change infusion to lactated Ringer's and maintain rate.
Correct Answer: C
Rationale: Correct Answer: C - Slow infusion rate and contact the provider.
Rationale: The client is showing signs of fluid volume overload with dyspnea, elevated blood pressure, and a significant fluid intake-output discrepancy. Slowing the infusion rate will help reduce fluid intake and potentially prevent worsening of the overload. Contacting the provider is crucial for further assessment and possible adjustment of the treatment plan.
Summary:
A: Lowering the head of the bed may help with respiratory distress but does not address the underlying issue of fluid overload.
B: Administering corticosteroids is not indicated for fluid overload and may worsen the situation.
D: Changing to lactated Ringer's does not address the immediate need to slow down the infusion rate and seek provider guidance.
A nurse is analyzing the ABG results of a client who is in respiratory acidosis. Which of the following mechanisms should the nurse identify as responsible for this acid-base imbalance?
- A. Retention of carbon dioxide
- B. Loss of bicarbonate
- C. Excessive vomiting
- D. Hyperventilation
Correct Answer: A
Rationale: The correct answer is A: Retention of carbon dioxide. In respiratory acidosis, there is an accumulation of carbon dioxide in the bloodstream due to inadequate ventilation. This leads to increased levels of carbonic acid, causing the blood pH to decrease. The nurse should identify this mechanism as responsible for the acid-base imbalance.
Loss of bicarbonate (B) would lead to metabolic acidosis, not respiratory acidosis. Excessive vomiting (C) would result in metabolic alkalosis. Hyperventilation (D) would actually help correct respiratory acidosis by blowing off excess carbon dioxide.
A PACU nurse is monitoring the drainage from a client's NG tube following abdominal surgery. Which of the following findings in the first postoperative hour should the nurse report to the provider?
- A. 100 mL of red drainage
- B. 75 mL of greenish-yellow drainage
- C. 200 mL of brown drainage
- D. 150 mL of serosanguineous drainage
Correct Answer: A
Rationale: The correct answer is A: 100 mL of red drainage. Red drainage from an NG tube may indicate active bleeding, which is a concerning finding post-abdominal surgery. This could suggest a potential internal bleeding or vascular injury. The nurse should report this finding to the provider immediately for further evaluation and intervention.
The other choices are incorrect because:
B: 75 mL of greenish-yellow drainage - This could be indicative of bile drainage, which is expected after abdominal surgery.
C: 200 mL of brown drainage - Brown drainage is likely due to old blood or bile, which can be normal in the immediate postoperative period.
D: 150 mL of serosanguineous drainage - Serosanguineous drainage is a mixture of blood and clear fluid, which can be expected after surgery.
Therefore, the correct answer is A due to the potential seriousness of active bleeding indicated by red drainage.
A nurse is planning care for a client who has a seizure disorder. Which of the following equipment should the nurse place in the client's room?
- A. NG tube
- B. Tongue blade
- C. Wrist restraints
- D. Oral airway
Correct Answer: D
Rationale: The correct answer is D: Oral airway. During a seizure, a client may experience difficulty breathing due to their airway being obstructed. Placing an oral airway helps maintain a clear airway, ensuring adequate oxygenation. NG tube (A) is not relevant to managing seizures. Tongue blade (B) can cause injury during a seizure. Wrist restraints (C) are not appropriate and can increase the risk of injury.
