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. A client with which of the following conditions is at risk for developing a high ammonia level?

• A. renal failure
• B. psoriasis
• C. lupus
• D. cirrhosis

Correct answer: D

Rationale: A client with cirrhosis is at risk for developing a high ammonia level due to impaired liver function. The liver normally converts ammonia into urea for excretion. In cirrhosis, this process is compromised, leading to elevated ammonia levels in the blood. Renal failure, psoriasis, and lupus do not typically cause high ammonia levels. Renal failure affects kidney function, while psoriasis and lupus are autoimmune conditions that do not directly impact ammonia metabolism.

3. Which of the following microorganisms are considered normal body flora?

• A. staphylococcus on the skin
• B. streptococcus in the nares
• C. candida albicans in the vagina
• D. pseudomonas in the blood

Correct answer: A

Rationale: Staphylococcus is considered normal body flora as it is commonly found on the skin, being a part of the normal microbiota. While streptococcus in the nares can be part of the normal flora of the upper respiratory tract, it is not as common or as widespread as staphylococcus on the skin. Candida albicans in the vagina is not considered normal flora; it is a common opportunistic pathogen in the vagina. Pseudomonas in the blood is also not considered normal body flora; pseudomonas is not typically found in the blood as part of the normal microbiota.

4. A client with dysphagia is ready to eat lunch. Which of these foods on the tray would be best to start with when assisting the client?

• A. diced fruit
• B. apple juice with a liquid thickener
• C. Jell-O�
• D. toast

Correct answer: B

Rationale: The correct choice is apple juice with a liquid thickener. A client with dysphagia is at risk for aspiration, so it is crucial to start with liquids and assess the client's ability to swallow before introducing solid foods. Using a liquid thickener with apple juice allows the healthcare provider to evaluate swallowing function. Jell-O�, although it melts into a clear liquid, should be avoided initially as it may not provide a clear assessment of swallowing ability. Diced fruit and toast are solid foods that should be introduced only after the client's swallowing ability with liquids has been assessed.

5. Which of the following medications should be held 24-48 hours prior to an electroencephalogram (EEG)?

• A. Lasix (furosemide)
• B. Cardizem (diltiazem)
• C. Lanoxin (digoxin)
• D. Dilantin (phenytoin)

Correct answer: D

Rationale: Anticonvulsants like Dilantin should be held 24-48 hours before an EEG to prevent interference with the test results. Medications such as tranquilizers, barbiturates, and other sedatives should also be avoided. Lasix, Cardizem, and Lanoxin do not belong to these categories and are not known to interfere with EEG results.
