What is the main characteristic of cystic fibrosis?
- A. Multiple upper respiratory infections
- B. An underproduction of exocrine glands
- C. Excessive, thick mucus
- D. An overproduction of thin mucus
Correct Answer: C
Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

A male client with Herpes Zoster (shingles) on his thorax tells the nurse that he is having difficulty sleeping. What is the etiology of this problem?
- A. Pain
- B. Nocturia
- C. Dyspnea
- D. Frequent cough
Correct Answer: A
Rationale: The correct answer is A: Pain. The pain caused by Herpes Zoster (shingles) can disrupt sleep patterns. It is a common symptom of shingles and can lead to difficulty falling asleep or staying asleep. Nocturia (B), dyspnea (C), and frequent cough (D) are not typically associated with shingles and would not directly cause difficulty sleeping in this scenario.
A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client's respiratory acidosis?
- A. Low oxygen levels are present in the blood.
- B. High levels of carbon dioxide have accumulated in the blood.
- C. Increased bicarbonate levels are causing alkalosis.
- D. Respiratory rate is increased, causing hyperventilation.
Correct Answer: B
Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.
The mother of a child with acute laryngotracheobronchitis (LTB) asks why her child must be kept NPO. Which response would be the most correct?
- A. The epinephrine given causes nausea and vomiting.
- B. The child is being hydrated with IV fluids.
- C. The child is not hungry.
- D. The child's rapid respirations pose a risk for aspiration.
Correct Answer: D
Rationale: The correct answer is D because rapid respirations predispose to aspiration in a child with acute laryngotracheobronchitis. Choice A is incorrect because epinephrine does not directly relate to the need for NPO status. Choice B is incorrect as hydration with IV fluids is not the primary reason for keeping the child NPO. Choice C is incorrect as the child being hungry is not the main concern when keeping a child NPO in this situation.
What are priority nursing interventions designed to do for a 4-year-old child with cerebral palsy?
- A. Assist with referral to specialized education.
- B. Support the child with independent toileting.
- C. Assist the child to develop effective communication.
- D. Encourage the child to ambulate independently.
Correct Answer: C
Rationale: The correct answer is C: 'Assist the child to develop effective communication.' Children with cerebral palsy often face challenges with communication skills. Therefore, priority nursing interventions aim to help them improve their communication abilities. Choice A is incorrect because while education is important, the priority for a child with cerebral palsy is to address immediate needs. Choice B is incorrect as toileting, although important, is not the priority in this case. Choice D is incorrect as ambulation may not be feasible or the most critical concern for a child with cerebral palsy.
A young adult male is admitted to the intensive care unit with multiple rib fractures and severe pulmonary contusions after falling 20 feet from a rooftop. The Chest X-ray suggests acute Respiratory distress Syndrome. Which assessment finding warrants immediate intervention by the Nurse?
- A. Apical pulse 58 bpm.
- B. Core body temperature 100.8°F.
- C. Tachypnea with dyspnea.
- D. Multiple bruises over the chest area.
Correct Answer: C
Rationale: In a patient with multiple rib fractures, severe pulmonary contusions, and possible acute Respiratory Distress Syndrome (ARDS), tachypnea (rapid breathing) with dyspnea (shortness of breath) is a critical sign of respiratory distress that warrants immediate intervention by the nurse. Tachypnea and dyspnea indicate inadequate oxygenation and ventilation, which can lead to respiratory failure if not addressed promptly. The other options, such as apical pulse rate, core body temperature, and bruises over the chest area, are important assessments but do not directly indicate the immediate need for intervention in a patient with respiratory distress.
