Nursing Elites

1. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?

• A. Frequency of laxative use for chronic constipation
• B. Dietary intake of magnesium-rich foods
• C. Use of magnesium-containing supplements
• D. History of alcohol use

Correct answer: A

Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.

2. A client with a history of chronic kidney disease is scheduled for a renal biopsy. Which laboratory value should the nurse report to the healthcare provider before the procedure?

• A. Serum creatinine of 1.8 mg/dl
• B. Prothrombin time of 18 seconds
• C. Hemoglobin of 9 g/dl
• D. Platelet count of 90,000/mm3

Correct answer: D

Rationale: A platelet count of 90,000/mm3 is low and concerning for a client scheduled for a renal biopsy, as it increases the risk of bleeding. Thrombocytopenia, indicated by a low platelet count, can lead to impaired blood clotting, posing a significant risk of bleeding during or after the biopsy procedure. Elevated serum creatinine levels may be expected in chronic kidney disease but are not directly related to bleeding risk during a renal biopsy. Prothrombin time and hemoglobin levels are not as directly relevant to the bleeding risk associated with a renal biopsy as platelet count.

3. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding is most concerning?

• A. Bradycardia
• B. Muscle weakness
• C. Peaked T waves on the ECG
• D. Decreased deep tendon reflexes

Correct answer: C

Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.

4. A male client with an antisocial personality disorder is admitted to an inpatient mental health unit for multiple substance dependencies. When providing a history, the client justifies to the nurse his use of illicit drugs. Based on this pattern of behavior, this client's history is most likely to include which finding?

• A. Multiple convictions for misdemeanors and class B felonies.
• B. A history of stable employment
• C. Strong relationships with family members
• D. A pattern of seeking help when needed

Correct answer: A

Rationale: The correct answer is A: Multiple convictions for misdemeanors and class B felonies. Clients with antisocial personality disorder often engage in behaviors that disregard societal rules and norms, leading to legal issues and criminal activities. This behavior is characteristic of individuals with antisocial personality disorder. Choices B, C, and D are incorrect because individuals with this disorder are less likely to have stable employment, strong family relationships, or seek help when needed due to their pattern of defiance and disregard for authority and rules.

5. The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?

• A. Serum creatinine of 1.5 mg/dL
• B. Serum sodium of 136 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Hemoglobin of 12 g/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.
