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 62-year-old female is being seen on a home visit by a nurse. The patient reports she has been taking Premarin for years. Which of the following would indicate an overdose?

• A. Lower extremity edema
• B. Sensory changes in the upper extremities
• C. Increased occurrence of fractures
• D. Decreased peripheral blood flow

Correct answer: A

Rationale: Lower extremity edema can indicate an overdose of Premarin. Premarin, an estrogen hormone replacement therapy, can cause fluid retention leading to edema in the lower extremities. Sensory changes in the upper extremities, increased occurrence of fractures, and decreased peripheral blood flow are not typically associated with an overdose of Premarin.

3. What type of cells create exocrine secretions?

• A. alpha cells
• B. beta cells
• C. acinar cells
• D. plasma cells

Correct answer: C

Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.

4. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.

5. A healthcare professional is reviewing a patient's current Lithium levels. Which of the following values is outside the therapeutic range?

• A. 1.0 mEq/L
• B. 1.1 mEq/L
• C. 1.2 mEq/L
• D. 1.3 mEq/L

Correct answer: D

Rationale: The correct answer is 1.3 mEq/L. The therapeutic range for Lithium levels typically falls between 0.6 to 1.2 mEq/L. Values below or above this range can lead to suboptimal treatment outcomes or toxicity. Choices A, B, and C are within the therapeutic range of 1.0-1.2 mEq/L, making them appropriate levels for patient care.
