Nursing Elites

1. The client is scheduled for a pericentesis. Which instruction should be given to the client before the exam?

• A. "You will need to lie flat during the exam."?
• B. "You need to empty your bladder before the procedure."?
• C. "You will be asleep during the procedure."?
• D. "The doctor will inject a medication to treat your illness during the procedure."?

Correct answer: B

Rationale: The client scheduled for a pericentesis should be instructed to empty the bladder to prevent the risk of bladder puncture when the needle is inserted. A pericentesis involves removing fluid from the peritoneal cavity. The client is typically positioned sitting up or leaning over a table, making answer A incorrect. During a pericentesis, the client is usually awake, so answer C is incorrect. Medications are not commonly injected into the peritoneal cavity during this procedure, making answer D incorrect. However, it's important to note that the administration of medications during the procedure could vary based on specific circumstances.

2. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

3. A client with cancer is admitted to the oncology unit. Stat lab values reveal Hgb 12.6, WBC 6500, K+ 1.9, uric acid 7.0, Na+ 136, and platelets 178,000. The nurse evaluates that the client is experiencing which of the following?

• A. Hypernatremia
• B. Hypokalemia
• C. Myelosuppression
• D. Leukocytosis

Correct answer: B

Rationale: The correct answer is 'Hypokalemia.' The potassium level of 1.9 indicates low potassium levels, a condition known as hypokalemia. The other lab values are within normal ranges: Hgb 12.6, WBC 6500, uric acid 7.0, Na+ 136, and platelets 178,000. Hypernatremia (choice A) refers to high sodium levels, which are not present in this case. Myelosuppression (choice C) is a decrease in bone marrow activity, which is not indicated by the lab values provided. Leukocytosis (choice D) is an increase in white blood cells, which is also not present based on the given values.

4. The client with schizophrenia has become disruptive and requires seclusion. Which staff member can institute seclusion?

• A. The security guard
• B. The registered nurse
• C. The licensed practical nurse
• D. The nursing assistant

Correct answer: B

Rationale: The registered nurse is the correct choice to institute seclusion for a client with schizophrenia. In healthcare settings, only a registered nurse or a physician can legally initiate seclusion. The security guard, licensed practical nurse, and nursing assistant do not have the authority to carry out this action. Therefore, options A, C, and D are incorrect.

5. How can medication bound to protein affect drug availability?

• A. enhanced drug availability
• B. rapid distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. increased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.
