Fundamentals of Nursing Oxygenation Questions Questions
Question 1 of 5
The client is experiencing severe shortness of breath,but is not cyanotic. What laboratory value should the nurse review in an attempt to understand this phenomenon?
Correct Answer: B
Rationale: Cyanosis requires at least 5 g/dL of unoxygenated hemoglobin and dilated surface capillaries. Severe anemia (low hemoglobin/hematocrit B) can prevent cyanosis despite hypoxia as insufficient hemoglobin limits visible deoxygenation. Blood sugar (A) cardiac enzymes (C) and electrolytes (D) do not explain the absence of cyanosis making B the relevant lab value to review.
Question 2 of 5
A client with a nasotracheal tube in place has been restless and pulling at the tube. How should the nurse assess if the tube is still in place?
Correct Answer: C
Rationale: The nasotracheal tube should sit above the tracheal bifurcation. Auscultating bilateral breath sounds (C) confirms correct placement as equal sounds indicate the tube is not dislodged or in a mainstem bronchus. Counting respirations (A) or assessing depth (B) does not verify tube position. Deflating the cuff (D) is unsafe and unnecessary making C the appropriate assessment method.
Question 3 of 5
A client has been prescribed both a bronchodilator and a steroid medication that is delivered by inhaler. What information is essential to teach this client in regard to these medications?
Correct Answer: D
Rationale: Bronchodilators and steroid inhalers can be used together with the bronchodilator typically first for immediate relief followed by the steroid for maintenance (A C incorrect). Steroids (B) are not for immediate effects as they reduce inflammation over time. Both medications (D) can increase heart rate a key side effect to monitor making D essential teaching for safety and compliance.
Question 4 of 5
An older client is prescribed diazepam (Valium). What should the nurse monitor in this client?
Correct Answer: A
Rationale: Diazepam a benzodiazepine can depress the respiratory center especially in older adults increasing risk of respiratory depression (A). Monitoring respirations is critical for safety. Urine output (B) muscle tone (C) and appetite (D) are not primarily affected by diazepam making A the essential parameter to monitor.
Question 5 of 5
The nurse documents that a prescribed expectorant has been effective for a client. What did the nurse evaluate in this client?
Correct Answer: D
Rationale: Expectorants thin mucus facilitating easier expectoration. A productive cough (D) indicates effectiveness as the client can expel secretions. Labored breathing (A) wheezing (B) and high-pitched cough (C) suggest ongoing issues not resolution making D the evaluated finding for expectorant efficacy.
