A nurse is making a follow-up call to a client who has a new prescription for an ACE Inhibitor to treat hypertension. The client reports lightheadedness upon standing. Which of the following statements should the nurse make?

Since the client is prescribed home oxygen at 1 to 2 L/min, a nasal cannula is the most appropriate device for oxygen delivery in this scenario. A nasal cannula consists of two small prongs that are inserted into the client's nostrils, delivering oxygen directly into the nasal passages. It is a comfortable and commonly used device for low-flow oxygen therapy.

Petroleum jelly is not directly related to oxygen therapy and is not typically required for the use of a nasal cannula.

A reservoir bag is not typically used with a nasal cannula. It is a component of a different oxygen delivery system called a non-rebreather mask, which is used for high-flow oxygen therapy or in emergency situations.

An oxygen mask is also not typically used with a nasal cannula. It is a separate oxygen delivery device that covers the client's mouth and nose, delivering oxygen at a higher flow rate. Masks may be used in situations where higher concentrations or flows of oxygen are required, or when the client is unable to tolerate or use a nasal cannula effectively.

Given the client's symptoms (productive cough, blood-tinged sputum, fatigue, night sweats, low-grade fever, weight loss, and recent travel to South Africa), there is a suspicion of tuberculosis (TB). The Mantoux test (a skin test for TB) and a chest X-ray are appropriate diagnostic tools to evaluate for TB.

A. a nasopharyngeal swab: This test is used to detect respiratory infections, but the client's symptoms and history do not specifically indicate the need for this test.

B. A pulmonary function test: While this test assesses lung function, it may not be the initial choice for evaluating the presented symptoms and history.
C. A chest x-ray
Rationale: Given the client's symptoms of cough, fatigue, night sweats, low-grade fever, and blood-tinged sputum, a chest x-ray is indicated to assess the condition of the lungs and potential underlying respiratory issues.
D. blood cultures
Rationale: The client's symptoms, including fever, could indicate an underlying infection. Blood cultures are used to identify potential bacterial or fungal infections in the bloodstream, but this is not likely for this patient
E. a Mantoux test
Rationale: The client's recent travel history, cough, and weight loss may prompt consideration of a tuberculosis (TB) infection. A Mantoux test is a common initial screening tool for TB exposure.
