Nursing Elites

1. The healthcare provider is caring for a client with a chest tube following a pneumothorax. Which assessment finding should be reported to the healthcare provider immediately?

• A. Continuous bubbling in the water seal chamber
• B. Absence of drainage in the collection chamber
• C. Tidaling in the water seal chamber
• D. Presence of subcutaneous emphysema around the insertion site

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber should be reported to the healthcare provider immediately. This finding may indicate an air leak, which can compromise the effectiveness of the chest tube in re-expanding the lung. Absence of drainage in the collection chamber (choice B) may signify that the chest tube is blocked, but it does not pose an immediate threat to the client's condition. Tidaling in the water seal chamber (choice C) is an expected finding and indicates proper functioning of the chest tube system. Presence of subcutaneous emphysema around the insertion site (choice D) suggests air leakage but is not as urgent as continuous bubbling in the water seal chamber.

2. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

3. Which structures are located in the subcutaneous layer of the skin?

• A. Sebaceous and sweat glands
• B. Melanin and keratin
• C. Sensory receptors and hair follicles
• D. Adipose cells and blood vessels

Correct answer: D

Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.

4. Following an open reduction of the tibia, the nurse notes fresh bleeding on the client's cast. What intervention should the nurse implement?

• A. Assess the client's hemoglobin levels to determine if the client is in shock
• B. Call the surgeon and prepare to take the client back to the operating room
• C. Outline the area with ink and check it every 15 minutes to monitor for changes in bleeding
• D. No action is required as postoperative bleeding can be expected

Correct answer: C

Rationale: In this scenario, the correct intervention is to outline the area with ink and check it every 15 minutes to monitor for changes in bleeding. This approach helps in assessing the extent and progression of the bleeding. Option A is incorrect because assessing hemoglobin levels would not provide immediate information on the ongoing bleeding. Option B is premature without first monitoring the bleeding site. Option D is incorrect because although some postoperative bleeding can be expected, fresh bleeding on the cast warrants immediate monitoring and evaluation.

5. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?

• A. Irrigate the catheter daily.
• B. Change the catheter every 72 hours.
• C. Apply antibiotic ointment at the insertion site.
• D. Ensure the catheter bag is always below bladder level.

Correct answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.
