1. A male client notifies the nurse that he feels short of breath and has chest pressure radiating down his left arm. A STAT 12-lead electrocardiogram (ECG) is obtained and shows ST segment elevation in leads II, III, aVF, and V4R. The nurse collects blood samples and gives a normal saline bolus. What action is most important for the nurse to implement?

A. Obtain the results for STAT serum cardiac biomarkers.
B. Assess for contraindications for thrombolytic therapy.
C. Measure ST-segment height and waveform changes.
D. Transfer for percutaneous coronary intervention (PCI).

Correct answer: B

Rationale: Assessing for contraindications for thrombolytic therapy is crucial as it determines whether the client is a candidate for reperfusion therapy. In this scenario, the client is presenting with symptoms and ECG changes consistent with an acute myocardial infarction (MI). Thrombolytic therapy aims at restoring blood flow to the heart muscle, reducing the size of the infarct. However, it is essential to assess for contraindications such as recent surgery, active bleeding, or a history of stroke to avoid potential complications. Obtaining serum cardiac biomarkers or measuring ST-segment changes are important steps in the diagnosis of MI but are not as time-sensitive as assessing for contraindications to thrombolytic therapy. Transfer for percutaneous coronary intervention (PCI) is a definitive treatment for MI, but assessing for thrombolytic therapy eligibility takes precedence in this acute situation.

2. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. She mentions that he was born two weeks after his due date and is a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?

A. Has your son had any immunizations yet?
B. Is your son sleepy and difficult to feed?
C. Are you breastfeeding or bottle feeding your son?
D. Were any relatives born with birth defects?

Correct answer: B

Rationale: The correct answer is B. Sleepiness and difficulty feeding are key signs of congenital hypothyroidism, which requires early diagnosis and treatment. Asking about immunizations (choice A) is important but not directly related to assessing hypothyroidism. The feeding method (choice C) is relevant for overall health but not specific to hypothyroidism. Inquiring about relatives with birth defects (choice D) is not the most crucial question to assess hypothyroidism in this scenario.

3. A client with chronic liver disease is admitted with ascites and jaundice. Which assessment finding is most concerning?

A. Enlarged spleen
B. Increased abdominal girth
C. Yellowing of the skin
D. Confusion and altered mental status

Correct answer: D

Rationale: Confusion and altered mental status are concerning in a client with chronic liver disease, as they may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Enlarged spleen (choice A) can be a common finding in liver disease due to portal hypertension but may not be as acute as hepatic encephalopathy. Increased abdominal girth (choice B) is typically seen in ascites, which is already present in this client. Yellowing of the skin (choice C) is a manifestation of jaundice, also a known symptom in liver disease but not as acute as confusion and altered mental status.

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 assessing a client with left-sided heart failure. Which finding is most concerning?

A. Jugular venous distention
B. Crackles in the lungs
C. Shortness of breath
D. Peripheral edema

Correct answer: C

Rationale: Shortness of breath is most concerning in a client with left-sided heart failure as it indicates pulmonary congestion, requiring immediate intervention. Jugular venous distention (Choice A) is a sign of increased central venous pressure but is not as concerning as pulmonary congestion. Crackles in the lungs (Choice B) are common in heart failure due to fluid accumulation but are not as immediately concerning as severe shortness of breath. Peripheral edema (Choice D) is a manifestation of fluid retention in the body but is less indicative of acute pulmonary distress compared to shortness of breath.
