Question 1 of 5
The nurse in a long-term care facility is planning the care for a client with a percutaneous endoscopic gastrostomy (PEG) feeding tube used for bolus feedings. Which intervention should the nurse include in the plan of care?
Correct Answer: B
Rationale: Elevating HOB post-feeding (
B) prevents aspiration in PEG clients. Naris inspection (
A) applies to NG tubes, Sims position (
C) is not standard, and dressings (
D) are changed PRN.
Question 2 of 5
Which diagnostic test should the nurse anticipate the health-care provider ordering to rule out the diagnosis of asthma in clients diagnosed with chronic obstructive pulmonary disease (COPD)?
Correct Answer: D
Rationale: A bronchodilator reversibility test differentiates asthma from COPD by assessing whether airway obstruction is reversible. In asthma, lung function (e.g., FEV1) improves significantly post-bronchodilator, while COPD shows minimal improvement. Bronchoscopy (
A) is invasive and not specific for this differentiation. Immunoglobulin E (
B) is relevant for allergies, not distinguishing asthma from COPD. Arterial blood gases (
C) assess oxygenation but do not differentiate these conditions.
Question 3 of 5
A 52-year old female patient is receiving medical treatment for a possible tuberculosis infection. The patient is a U.S. resident but grew up in a foreign country. She reports that as a child she received the BCG vaccine (bacille Calmette-Guerin vaccine). Which physician's order below would require the nurse to ask the doctor for an order clarification?
Correct Answer: A
Rationale: The BCG vaccine can cause false-positive PPD (Mantoux) test results, making it unreliable in patients with a BCG history. The nurse should clarify this order, as an IGRA test (e.g., QuantiFERON-TB Gold) or other diagnostics are preferred.
Question 4 of 5
When the nurse is teaching a client to self-administer nose drops, which head position is appropriate?
Correct Answer: C
Rationale: Tilting the head backward allows nose drops to reach the nasal passages effectively by gravity, ensuring proper distribution of the medication.
Question 5 of 5
A client comes to the clinic with a bloody nose. Which instruction is most appropriate?
Correct Answer: A
Rationale: Sitting with the head tilted forward and grasping the soft part of the nose prevents aspiration of blood and effectively stops bleeding.
