Nursing Elites

1. Sublingual nitroglycerin is administered to a male client with unstable angina who complains of crushing chest pain. Five minutes later the client becomes nauseated, and his blood pressure drops to 60/40. Which intervention should the nurse implement?

• A. Administer a second dose of nitroglycerin.
• B. Infuse a rapid IV normal saline bolus.
• C. Begin external chest compressions.
• D. Give a PRN antiemetic medication.

Correct answer: B

Rationale: In this scenario, the client's symptoms of nausea and a significant drop in blood pressure suggest a potential right ventricular infarction. The appropriate intervention for this situation is to infuse a rapid IV normal saline bolus. This fluid resuscitation helps improve cardiac output by increasing preload, which can be beneficial in right ventricular infarction. Administering a second dose of nitroglycerin may further lower blood pressure. External chest compressions are not indicated in this case as the client has a pulse. Providing an antiemetic medication does not address the underlying issue of hypotension and potential right ventricular involvement.

2. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

3. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding is most concerning?

• A. Serum glucose of 500 mg/dL
• B. Serum glucose of 600 mg/dL
• C. Serum potassium of 5.5 mEq/L
• D. Serum bicarbonate of 18 mEq/L

Correct answer: D

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.

4. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning?

• A. Serum glucose of 500 mg/dl
• B. Blood pressure of 140/90 mmHg
• C. Serum osmolarity of 320 mOsm/kg
• D. Serum pH of 7.30

Correct answer: C

Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS). This level of osmolarity indicates severe dehydration and hyperosmolarity, putting the client at risk of complications like organ failure. Immediate intervention is crucial to address the dehydration and restore fluid balance. The other options, while important in the overall assessment of a client with HHS, do not directly indicate the severity of dehydration and hyperosmolarity seen with a high serum osmolarity level.

5. The nurse is teaching a male client with multiple sclerosis how to empty his bladder using the Crede Method. When performing a return demonstration, the client applies pressure to the umbilical areas of his abdomen. What instruction should the nurse provide?

• A. Stroke the inner thigh below the perineum to initiate urinary flow
• B. Contract, hold, and then relax the pubococcygeal muscle
• C. Pour warm water over the external sphincter at the distal glans
• D. Apply downward manual pressure at the suprapubic regions

Correct answer: D

Rationale: The client is applying pressure in the wrong region (umbilical area) and should be instructed to apply pressure at the suprapubic area. Applying downward manual pressure at the suprapubic region helps in emptying the bladder effectively by assisting in pushing the urine out through the urethra. Choices A, B, and C are incorrect because they do not address the specific issue of applying pressure to help empty the bladder using the Crede Method.
