1. Which of the following symptoms is most characteristic of a client with lung cancer?

• A. exertional dyspnea
• B. persistent changing cough
• C. air hunger; dyspnea
• D. cough with night sweats

Correct answer: B

Rationale: The most characteristic symptom of lung cancer is a persistent changing cough. This cough may worsen over time and may produce blood-tinged sputum. Exertional dyspnea (Choice A) is more common in chronic obstructive pulmonary disease (COPD) due to airway obstruction. Air hunger and dyspnea (Choice C) are more typical of conditions like asthma. Cough with night sweats (Choice D) is commonly associated with tuberculosis rather than lung cancer.

2. A patient has suffered a left CVA and developed severe hemiparesis resulting in a loss of mobility. The nurse notices on assessment that an area over the patient's left elbow appears as non-blanchable erythema, and the skin is intact. The nurse should score the patient as having which of the following?

• A. Stage I pressure ulcer
• B. Stage II pressure ulcer
• C. Stage III pressure ulcer
• D. Stage IV pressure ulcer

Correct answer: A

Rationale: Erythema with the skin intact is characteristic of a Stage I pressure ulcer. At this stage, the skin is not broken, but there is localized redness that does not blanch when pressed. Stage II pressure ulcers involve partial-thickness skin loss, Stage III pressure ulcers have full-thickness skin loss, and Stage IV pressure ulcers extend to deeper tissues, including muscle and bone. In this case, the non-blanchable erythema with intact skin aligns with the characteristics of a Stage I pressure ulcer.

3. During a stress test, a patient complains of severe chest pain. Which of the following medications is the most appropriate to relieve this discomfort?

• A. Aspirin
• B. Diazoxide
• C. Procardia
• D. Mannitol

Correct answer: C

Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.

4. Which of the following medications is not classified as a neuromuscular blocker?

• A. Anectine
• B. Pavulon
• C. Pitressin
• D. Mivacron

Correct answer: C

Rationale: The correct answer is Pitressin. Pitressin is a hormone replacement medication and is not classified as a neuromuscular blocker. Choices A, B, and D (Anectine, Pavulon, Mivacron) are neuromuscular blockers used during anesthesia to induce muscle relaxation for various procedures. Anectine is also known as succinylcholine, Pavulon is rocuronium, and Mivacron is mivacurium. These medications act on the neuromuscular junction to block the transmission of nerve impulses, leading to muscle relaxation.

5. What are the major electrolytes in the extracellular fluid?

• A. potassium and chloride
• B. potassium and phosphate
• C. sodium and chloride
• D. sodium and phosphate

Correct answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.
