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.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

2. Which sign might a healthcare professional observe in a client with a high ammonia level?

• A. coma
• B. edema
• C. hypoxia
• D. polyuria

Correct answer: A

Rationale: A high ammonia level can lead to hepatic encephalopathy, which includes symptoms like confusion, disorientation, and can progress to coma. Coma is a severe condition of unconsciousness. Edema is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia is a condition of inadequate oxygen supply to tissues and organs, not directly related to high ammonia levels. Polyuria is excessive urination, which is not a typical sign of high ammonia levels.

3. After delivery, a newborn undergoes an Apgar assessment. What does this scoring system evaluate?

• A. heart rate, respiratory effort, color, muscle tone, reflex irritability
• B. heart rate, bleeding, cyanosis, edema
• C. bleeding, reflex, edema
• D. respiratory effort, heart rate, seizures

Correct answer: B

Rationale: The Apgar scoring system, developed by Virginia Apgar, an anesthesiologist, evaluates newborns based on five criteria: heart rate, respiratory effort, color, muscle tone, and reflex irritability. These parameters provide a quick and simple assessment of a newborn's overall condition and the need for immediate medical attention. Choices B, C, and D are incorrect as they do not encompass the essential elements evaluated by the Apgar scoring system.

4. When observing a dressing change by a graduate nurse on a Stage III pressure ulcer to the greater trochanter by the staff nurse, a need for further teaching is indicated after the following observation by the nurse:

• A. The new graduate nurse irrigates the pressure ulcer with 50cc of NS.
• B. The new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide.
• C. The new graduate packs the wound with sterile kerlix soaked in NS.
• D. The new graduate applies a Duoderm dressing over the wound after cleansing.

Correct answer: B

Rationale: The correct answer is that the new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide. Pressure ulcers should not be cleaned with substances that are cytotoxic, such as hydrogen peroxide or betadine. This can cause further damage to the wound and delay the healing process. Choice A is incorrect because irrigating the pressure ulcer with normal saline is an appropriate practice. Choice C is incorrect because packing the wound with sterile kerlix soaked in normal saline is also an appropriate step. Choice D is incorrect because applying a Duoderm dressing after cleansing is a standard procedure in wound care.

5. What can happen if a restraint is attached to a side rail or other movable part of the bed?

• A. Do nothing to the client.
• B. Injure the client if the rail or bed is moved.
• C. Help the client stay in the bed without falling out.
• D. Help the client with better posture.

Correct answer: B

Rationale: Attaching a restraint to a movable part of the bed can lead to client injury if that part of the bed is moved before releasing restraints. This could result in the client getting caught or trapped, possibly causing harm. Choices C and D are incorrect because attaching restraints to movable parts of the bed is not intended to help the client stay in bed or improve posture; rather, it poses a risk of injury. Choice A is incorrect as it does not address the potential harm associated with using restraints on movable parts of the bed.
