HESI RN
HESI 799 RN Exit Exam Capstone
1. A client is admitted with a suspected gastrointestinal bleed. What assessment finding requires immediate intervention?
- A. Bright red blood in the vomit.
- B. Elevated blood pressure and heart rate.
- C. Coffee ground emesis.
- D. Dark, tarry stools.
Correct answer: D
Rationale: Dark, tarry stools indicate the presence of digested blood in the gastrointestinal tract, signifying a higher gastrointestinal bleed. This finding requires immediate intervention due to the potential severity of the bleed. Bright red blood in the vomit may indicate active bleeding but is not as concerning as digested blood. Elevated blood pressure and heart rate are common responses to bleeding but do not provide direct evidence of the source or severity of the bleed. Coffee ground emesis is indicative of partially digested blood and is a concern but not as urgent as dark, tarry stools.
2. A client receives a prescription for 1 liter of lactated Ringer's intravenously to be infused over 6 hours. How many mL/hr should the nurse program the infusion pump to deliver? (Enter numerical value only. If rounding is needed, round to the nearest whole number.)
- A. 167 mL/hr
- B. 200 mL/hr
- C. 83 mL/hr
- D. 111 mL/hr
Correct answer: A
Rationale: The correct infusion rate is 167 mL/hr. This is calculated by dividing the total volume (1000 mL) by the total time (6 hours), resulting in 166.67 mL/hr, which should be rounded to the nearest whole number as 167 mL/hr. This calculation ensures a steady infusion rate over the specified time frame. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation based on the volume and time provided in the prescription.
3. An older client recently has been taking cimetidine (Tagamet). The nurse monitors the client for which most frequent central nervous system side effect of this medication?
- A. Tremors
- B. Dizziness
- C. Confusion
- D. Hallucinations
Correct answer: C
Rationale: Older clients are particularly vulnerable to central nervous system side effects of cimetidine. The most frequent side effect is confusion. It is crucial for nurses to be vigilant in monitoring for confusion as it can impact the client's safety and well-being. While tremors, dizziness, and hallucinations are possible side effects, confusion is the most common in older clients taking cimetidine.
4. The client is reviewing the signed operative consent with a nurse, who is admitted for the removal of a lipoma on the left leg. The client states that the consent form should say the removal of a lipoma on the right leg. Which intervention should the nurse implement?
- A. Notify the surgical team of the client’s confusion
- B. Have the client sign a new surgical consent
- C. Add the correct leg information to the consent form
- D. Inform the surgeon about the client’s concern
Correct answer: D
Rationale: In this scenario, the nurse should inform the surgeon about the client’s concern immediately. This is important to ensure that the correct procedure is performed on the intended leg. Communication with the surgeon is crucial to address any discrepancies in the consent form and prevent errors during the surgical procedure. Having the surgeon clarify and correct the consent form is essential to maintain patient safety and uphold the principles of informed consent.
5. How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: D
Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.
