Nursing Elites

1. 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.

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. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding requires immediate intervention?

• A. Barrel-shaped chest
• B. Use of accessory muscles
• C. Oxygen saturation of 85%
• D. Inspiratory crackles

Correct answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and requires immediate intervention to prevent hypoxemia. Oxygen saturation below 90% indicates poor oxygenation and poses a risk of tissue hypoxia, making it a critical finding that needs prompt attention. Barrel-shaped chest and inspiratory crackles are commonly seen in clients with COPD and do not necessitate immediate intervention. The use of accessory muscles may indicate increased work of breathing but does not pose the same level of immediate threat as severe hypoxemia.

4. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Serum glucose level
• C. White blood cell count
• D. Prothrombin time (PT)

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

5. An adolescent's mother calls the clinic because the teen is having recurrent vomiting and has become combative in the last 2 days. The mother states that the teen takes vitamins, calcium, magnesium, and aspirin. Which nursing intervention has the highest priority?

• A. Advise the mother to withhold all medications by mouth.
• B. Instruct the mother to take the teen to the emergency room.
• C. Recommend that the teen withhold food and fluids for 2 hours.
• D. Suggest that the adolescent breathe slowly and deeply.

Correct answer: B

Rationale: The correct answer is to instruct the mother to take the teen to the emergency room. The symptoms described, including recurrent vomiting and becoming combative after taking vitamins, calcium, magnesium, and aspirin, indicate a potential overdose or a serious condition. Therefore, immediate medical evaluation in the emergency room is crucial. Advising to withhold all medications by mouth (Choice A) may delay necessary treatment. Recommending to withhold food and fluids (Choice C) is not appropriate in this urgent situation. Suggesting deep breathing (Choice D) does not address the seriousness of the symptoms and the need for immediate medical attention.
