Health Promotion and Maintenance NCLEX RN Questions - Nurselytic

Correct Answer: C

Rationale: Chest pain, dyspnea, tachypnea, mild fever, and rales or crackles on auscultation in a client who had surgery 2 days ago may be indicative of a pulmonary embolism. The nurse should administer oxygen to address his breathing and assist him to a comfortable position to facilitate better oxygenation before contacting the physician. Placing the client in the Trendelenburg position is not recommended in this situation as it may worsen a potential pulmonary embolism by increasing venous return. Contacting the physician for antibiotics is not the priority as the immediate concern is addressing the breathing difficulty. Decreasing the IV rate is not indicated in this situation where the client is experiencing respiratory distress and needs oxygen therapy.

Correct Answer: A

Rationale: Substances that are irritating to the client with hiatal hernia include tomato products and citrus fruits, which should be avoided. Because caffeine stimulates gastric acid secretion, beverages that contain caffeine, such as coffee, tea, cola, and cocoa, are also eliminated from the diet.

Correct Answer: C

Rationale: The water seal of a chest tube acts as a one-way valve. Air bubbles in the water seal indicate a leak between the client and the chamber. The nurse should briefly clamp the tube near the client's chest to locate the source of the leak. Once identified, the nurse should unclamp the tubing and notify the physician immediately.

Choice A is incorrect because air bubbles in the water seal chamber are not a normal finding and indicate a leak.
Choice B is incorrect as stripping the tubing could aggravate the issue and is not the initial appropriate action.
Choice D is incorrect as it does not address the immediate need to locate and address the leak.

Correct Answer: B

Rationale: The client should inspect all surfaces of the residual limb daily for irritation, blisters, and breakdown. The client should wear a clean woolen (not nylon) sock each day. The residual limb is cleansed daily with a gentle soap and water and dried carefully. Alcohol is avoided because it could cause drying or cracking of the skin. Oils and creams are also avoided because they are too softening to the skin for safe prosthesis use.

Correct Answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue.
Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes.
Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages.
Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.
