Nursing Elites

1. A patient asks a nurse the following question: Exposure to TB can be best identified with which of the following procedures?

• A. Chest x-ray
• B. Mantoux test
• C. Breath sounds examination
• D. Sputum culture for Mycobacterium tuberculosis

Correct answer: B

Rationale: The Mantoux test, also known as the tuberculin skin test, is the most appropriate and accurate test to identify exposure to TB. This test involves injecting a small amount of PPD tuberculin under the top layer of the skin, and a positive reaction indicates exposure to the TB bacteria. Choice A, a chest x-ray, is useful for detecting active TB disease but not exposure. Choice C, a breath sounds examination, is not a specific test for TB exposure. Choice D, a sputum culture for Mycobacterium tuberculosis, is used to diagnose active TB infection rather than exposure.

2. Which of the following blood pressure parameters indicates PIH? Elevation over a baseline of:

• A. 30 mmHg systolic and/or 15 mmHg diastolic.
• B. 40 mmHg systolic and/or 20 mmHg diastolic.
• C. 10 mmHg systolic and/or 5 mmHg diastolic.
• D. 20 mmHg systolic and/or 20 mmHg diastolic.

Correct answer: A

Rationale: The correct answer is A: 30 mmHg systolic and/or 15 mmHg diastolic. These parameters indicate mild PIH (pregnancy-induced hypertension). Mild preeclampsia is characterized by an increase in systolic blood pressure greater than 30 mmHg or an increase in diastolic blood pressure greater than 15 mmHg, observed on two readings taken 6 hours apart (or reaching 140/90). Choice B (40 mmHg systolic and/or 20 mmHg diastolic) represents a more significant elevation and would indicate a more severe condition than mild PIH. Choices C (10 mmHg systolic and/or 5 mmHg diastolic) and D (20 mmHg systolic and/or 20 mmHg diastolic) do not meet the criteria for indicating PIH as they are below the accepted parameters for mild PIH.

3. The client is undergoing progressive ambulation on the third day after a myocardial infarction. Which clinical manifestation would indicate that the client should not be advanced to the next level?

• A. Facial flushing
• B. A complaint of chest heaviness
• C. Heart rate increase of 10 beats/min
• D. Systolic blood pressure increase of 10 mm Hg

Correct answer: B

Rationale: The correct answer is a complaint of chest heaviness. Onset of chest pain indicates myocardial ischemia, which can be life-threatening. Chest pain in a client post-myocardial infarction should be promptly evaluated, and the activity level should not be advanced. Choices A, C, and D are not the best options because facial flushing, a heart rate increase of 10 beats/min, and a systolic blood pressure increase of 10 mm Hg are not typical indicators of myocardial ischemia or necessarily contraindications for advancing activity levels in this context.

4. A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:

• A. increased therapeutic effects of Drug A.
• B. increased adverse effects of Drug B.
• C. decreased therapeutic effects of Drug A.
• D. decreased therapeutic effects of Drug B.

Correct answer: C

Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.

5. A patient has been diagnosed with diabetes mellitus. Which of the following is not a clinical sign of diabetes mellitus?

• A. Polyphagia
• B. Polyuria
• C. Metabolic acidosis
• D. Lower extremity edema

Correct answer: D

Rationale: Polyphagia, polyuria, and metabolic acidosis are common clinical signs of diabetes mellitus. Polyphagia refers to excessive hunger, polyuria is excessive urination, and metabolic acidosis can occur due to poorly controlled diabetes. Lower extremity edema, on the other hand, is not a typical clinical sign of diabetes mellitus. Edema in the lower extremities is more commonly associated with conditions like heart failure or kidney disease rather than diabetes mellitus.
