HESI 799 RN Exit Exam
1. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which intervention should the nurse implement first?
- A. Elevate the head of the bed.
- B. Administer oxygen therapy as prescribed.
- C. Assess the client's oxygen saturation.
- D. Obtain an arterial blood gas (ABG) sample.
Correct answer: C
Rationale: Assessing the client's oxygen saturation is the first priority in managing a client with COPD receiving supplemental oxygen to ensure adequate oxygenation. Monitoring oxygen saturation levels helps in determining the effectiveness of the oxygen therapy and if adjustments are needed. Elevating the head of the bed can help with breathing but is not the first priority. Administering oxygen therapy as prescribed is important, but assessing the current oxygen saturation comes before administering more oxygen. Obtaining an arterial blood gas (ABG) sample may provide valuable information, but it is not the initial intervention needed in this situation.
2. A 26-year-old female client is admitted to the hospital for treatment of a simple goiter, and levothyroxine sodium (Synthroid) is prescribed. Which symptoms indicate to the nurse that the prescribed dosage is too high for this client?
- A. Palpitations and shortness of breath
- B. Bradycardia and constipation
- C. Lethargy and lack of appetite
- D. Muscle cramping and dry, flushed skin
Correct answer: A
Rationale: The correct answer is A. An overdose of thyroid preparation generally manifests symptoms of an agitated state such as tremors, palpitations, shortness of breath, tachycardia, increased appetite, agitation, sweating, and diarrhea. Palpitations and shortness of breath are signs of excessive thyroid medication. Choices B, C, and D are incorrect symptoms for a dosage that is too high. Bradycardia and constipation, lethargy and lack of appetite, muscle cramping and dry, flushed skin are more indicative of hypothyroidism or an insufficient dosage of levothyroxine.
3. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?
- A. Serum sodium of 135 mEq/L
- B. Serum potassium of 4.0 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Serum glucose of 300 mg/dL
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.
4. The nurse is caring for a client with a history of myocardial infarction who is complaining of chest pain. Which intervention should the nurse implement first?
- A. Administer oxygen therapy as prescribed.
- B. Administer nitroglycerin sublingually as prescribed.
- C. Obtain an electrocardiogram (ECG).
- D. Assess the client's level of consciousness.
Correct answer: C
Rationale: Obtaining an electrocardiogram (ECG) is the first priority in assessing for ischemia or infarction in a client with chest pain and a history of myocardial infarction. This diagnostic test provides crucial information about the heart's electrical activity and helps in identifying any acute cardiac changes. Administering oxygen therapy and nitroglycerin can be important interventions, but obtaining an ECG takes precedence as it directly assesses the client's cardiac status. Assessing the client's level of consciousness is also essential, but in this scenario, assessing for cardiac indications through an ECG is the initial step.
5. 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.
