Pharmacology and the Nursing Process Test Bank

Correct Answer: A

Rationale: The correct answer is A: Inform the physician. This is essential because a sudden change in vital signs may indicate a critical condition that requires immediate medical attention. The physician needs to be informed promptly to assess the situation and provide appropriate interventions. Summary: - B: Changing environmental settings is not a priority when dealing with sudden changes in vital signs. - C: Altering diet intake is not an immediate response to sudden changes in vital signs. - D: Decreasing physical activity may not address the underlying cause of the sudden change in vital signs.

Correct Answer: C

Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This process helps in identifying any discrepancies or errors in the data. By cross-referencing with other sources, the nurse can verify the correctness of the data. Rationale: 1. Data validation checks the accuracy of the data by comparing it with external sources. 2. Data interpretation involves analyzing and making sense of the data, not comparing it with other sources. 3. Option A is incorrect because data validation typically comes after data collection and precedes data interpretation. 4. Option B is incorrect as validation does not specifically involve looking for patterns in professional standards. 5. Option D is incorrect because data interpretation focuses on understanding trends and insights from the data, not patterns in professional standards.

Correct Answer: B

Rationale: The correct answer is B: Pericardial friction rub. This is a key diagnostic sign of pericarditis due to the inflammation of the pericardial layers causing a rough, grating sound heard upon auscultation. Precordial pain (A) is a common symptom but not a specific diagnostic sign. Hypotension (C) and rapid/labored respirations (D) are not typically associated with pericarditis. Therefore, the presence of a pericardial friction rub is crucial in confirming the diagnosis of pericarditis.

Correct Answer: B

Rationale: Step 1: TIS stands for carcinoma in situ, which means cancer cells are present only in the layer of cells where they first developed. Step 2: N0 indicates no abnormal regional lymph nodes are involved. Step 3: M0 signifies no evidence of distant metastasis. Therefore, the correct answer is B because it accurately interprets the TNM staging system for the biopsy report. Summary: A: Incorrect - TIS indicates carcinoma in situ, not no evidence of primary tumor. C: Incorrect - TIS already assesses tumor presence, ruling out this option. D: Incorrect - TIS is not about ascending degrees of distant metastasis.

Correct Answer: C

Rationale: Correct Answer: C - Dryness of mouth Rationale: 1. Trihexyphenidyl is an anticholinergic medication commonly used to treat Parkinson's disease. 2. Anticholinergic drugs inhibit the parasympathetic nervous system, leading to decreased secretions. 3. Dryness of mouth (xerostomia) is a common side effect of anticholinergic medications. 4. Excessive salivation, bradycardia, and constipation are not typically associated with anticholinergic drugs, making them incorrect choices.
