Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value is most concerning?

• A. Serum potassium of 6.5 mEq/L
• B. Serum bicarbonate of 18 mEq/L
• C. Serum glucose of 350 mg/dl
• D. Serum sodium of 135 mEq/L

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with COPD exacerbation as it may lead to life-threatening arrhythmias, requiring immediate intervention. Hyperkalemia can cause cardiac arrhythmias, which pose a significant risk to the patient's life. Options B, C, and D are not typically associated with immediate life-threatening risks in the context of a COPD exacerbation.

2. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?

• A. Slide the stethoscope across the sternum.
• B. Move the stethoscope to the mitral site.
• C. Listen with the bell at the same location.
• D. Observe the cardiac telemetry monitor.

Correct answer: C

Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.

3. The nurse is triaging several children as they present to the emergency room after an accident. Which child requires the most immediate intervention by the nurse?

• A. An 11-year-old with a headache, nausea, and projectile vomiting
• B. A 5-year-old with a broken arm
• C. A 7-year-old with minor abrasions
• D. A 9-year-old with a twisted ankle

Correct answer: A

Rationale: The correct answer is A. Projectile vomiting in a child with a headache could indicate increased intracranial pressure, requiring immediate attention. Choices B, C, and D do not present with symptoms indicating potentially life-threatening conditions that require urgent intervention.

4. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning to the nurse?

• A. Barrel-shaped chest
• B. Use of accessory muscles
• C. Oxygen saturation of 85%
• D. Respiratory rate of 28 breaths per minute

Correct answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.

5. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value requires immediate intervention?

• A. Serum glucose of 600 mg/dL
• B. Serum osmolarity of 320 mOsm/kg
• C. Serum sodium of 130 mEq/L
• D. Serum potassium of 5.0 mEq/L

Correct answer: B

Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.
