Question 1 of 5
Which of the following could the nurse expect to observe in an older adult client who has a pneumothorax?
Correct Answer: A
Rationale: A pneumothorax impairs gas exchange, causing lower oxygen saturations (93%-94%) due to lung collapse. Higher saturations, lower energy use, or increased lung capacity are not expected.
Question 2 of 5
A nurse is reinforcing teaching for a client who presents with a pulmonary embolism. Which of the following information should the nurse provide?
Correct Answer: D
Rationale: All pulmonary embolisms require treatment, typically anticoagulation, to prevent progression or recurrence, regardless of symptoms or stability, due to the risk of complications.
Question 3 of 5
Order: Diphenhydramine 25mg Q4H Available: Diphenhydramine 12.5mg/5mL How much will you administer?
Correct Answer: 10 mL
Rationale:
To administer 25 mg of diphenhydramine (12.5 mg/5 mL), calculate: 25 mg ÷ 2.5 mg/mL = 10 mL. Thus, 10 mL is the correct dose.
Question 4 of 5
A nurse is assisting with the care of a client who has multiple injuries following a motor vehicle crash. The nurse should monitor for which of the following manifestations of a pneumothorax?
Correct Answer: C
Rationale: A pneumothorax causes lung collapse, leading to an absence of breath sounds over the affected area due to air in the pleural space preventing lung expansion. Stridor, wheezes, and crackles are associated with upper airway obstruction, bronchoconstriction, or fluid/mucus, respectively.
Question 5 of 5
A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?
Correct Answer: B
Rationale: A spacer enhances lung delivery of MDI medication by slowing aerosol and reducing oropharyngeal deposition. Slow inhalation and open exhalation slots optimize use.
