Nursing Elites

1. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

2. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

3. What is distraction therapy?

• A. Focusing one's attention on stimuli other than pain.
• B. Cognitive reappraisal.
• C. The replacement of positive images of pain with other images.
• D. The use of medication and meditation.

Correct answer: A

Rationale: Distraction therapy involves directing attention away from pain towards positive stimuli, which can help reduce the perception of pain. Choice A is the correct answer as it accurately defines distraction therapy. Cognitive reappraisal (Choice B) involves changing the way one thinks about a situation to alter its emotional impact, which is different from distraction therapy. Choice C is incorrect because distraction therapy does not involve replacing images of pain with other images, but rather focusing on something unrelated. Choice D is incorrect as distraction therapy does not necessarily involve medication or meditation, but rather the redirection of attention.

4. When are pressure ulcers most likely to occur?

• A. when clients are left in one position in bed for extended periods of time.
• B. when clients are underweight.
• C. when clients are overweight.
• D. only in underweight and overweight clients.

Correct answer: A

Rationale: Pressure ulcers usually occur over bony prominences and are caused by decreased circulation. The client who is left in one position in bed for extended periods of time is more prone to decreased circulation to an area of the body and to acquiring a pressure ulcer. Choices B and C are incorrect as pressure ulcers are not exclusive to underweight or overweight clients. The key factor is prolonged pressure on the skin, not the weight of the client. Therefore, the correct answer is that pressure ulcers are most likely to occur when clients are immobilized in one position for extended periods of time.

5. A nurse is preparing to administer medications to a client via a nasogastric (NG) tube. Before administering the medication, the nurse must first take which action?

• A. Check the client's apical pulse
• B. Check when the last feeding was given
• C. Check the placement of the tube
• D. Check when the last medications were given

Correct answer: C

Rationale: Before administering medications through an NG tube, the nurse must first check the placement of the tube to prevent aspiration. This is done by aspirating gastric contents and measuring the pH. Checking the client's apical pulse is unrelated to NG tube medication administration. Checking when the last feeding was given is important but not a priority before administering medications. Checking when the last medications were given is also not directly related to ensuring the safe administration of medications through an NG tube. Ensuring the correct placement of the tube is crucial to prevent complications such as pulmonary aspiration.
