A nurse is caring for a client who has an indwelling catheter with a urinary drainage system. Which of the following actions should the nurse take?

Rationale for correct choices:

• A Mantoux test: The client presents with a chronic productive cough, night sweats, low-grade fever, hemoptysis, recent weight loss, and recent travel to South Africa, which is a region with higher tuberculosis prevalence. A Mantoux test helps screen for Mycobacterium tuberculosis infection. These systemic and respiratory findings strongly support the need for TB evaluation.

• A chest xray: A chest xray is essential for evaluating pulmonary pathology when tuberculosis is suspected. It can reveal cavitary lesions, infiltrates, or consolidation consistent with active TB disease. Imaging is necessary to assess disease severity and guide further diagnostic testing and isolation precautions.

Rationale for incorrect choices:

• Blood cultures: Blood cultures are primarily used to identify systemic bloodstream infections or sepsis. This client’s presentation is localized to the respiratory system without signs of hemodynamic instability or systemic bacterial infection. Blood cultures would not be a priority for initial TB evaluation.

• A pulmonary function test: Pulmonary function tests assess chronic airflow or restrictive lung diseases such as asthma or COPD. They are not appropriate in the acute evaluation of suspected infectious diseases like tuberculosis. Performing PFTs would not help identify the cause of hemoptysis or constitutional symptoms.

• A nasopharyngeal swab: Nasopharyngeal swabs are used to detect viral respiratory infections such as influenza or COVID-19. The client’s prolonged symptoms, weight loss, night sweats, and hemoptysis are not consistent with an acute viral illness. TB evaluation requires targeted testing rather than upper airway swabs.

A. Garlic: Garlic has been shown to have lipid-lowering properties, helping reduce total cholesterol and low-density lipoprotein (LDL) levels. It is commonly recommended as an adjunct to lifestyle modifications for clients with hypercholesterolemia. Its use should be monitored for interactions with anticoagulants or antiplatelet medications.

B. Valerian root: Valerian root is primarily used for promoting relaxation and improving sleep quality. It does not have evidence supporting cholesterol-lowering effects and would not address elevated lipid levels.

C. Saw palmetto: Saw palmetto is used mainly to manage benign prostatic hyperplasia (BPH) symptoms in men. It does not influence cholesterol metabolism or lipid profiles and is not indicated for hypercholesterolemia.

D. Aloe: Aloe is typically used for skin conditions or as a laxative. While it has some antioxidant properties, it is not effective in lowering cholesterol and is not recommended for managing hyperlipidemia.
