HESI RN
HESI Fundamentals
1. The nurse observes an unlicensed assistive personnel (UAP) taking a client's blood pressure with a cuff that is too small, but the blood pressure reading obtained is within the client's usual range. What action is most important for the nurse to implement?
- A. Tell the UAP to use a larger cuff at the next scheduled assessment.
- B. Reassess the client's blood pressure using a larger cuff.
- C. Have the unit educator review this procedure with the UAPs.
- D. Teach the UAP the correct technique for assessing blood pressure.
Correct answer: B
Rationale: The most important action is to ensure that an accurate BP reading is obtained. The nurse should reassess the blood pressure with the correct size cuff (B) to obtain an accurate reading. Postponing reassessment (A) could lead to inaccurate results. While (C and D) are important actions for education and quality improvement, they are not as critical as obtaining an accurate blood pressure reading in this situation.
2. How should the caregiver instruct on caring for a 4-month-old with seborrheic dermatitis (cradle cap) when shampooing the child's hair?
- A. Use a soft brush and gently scrub the area.
- B. Avoid scrubbing the scalp until the scales disappear.
- C. Avoid washing the child's hair more than once a week.
- D. Use soap and water and avoid shampoos.
Correct answer: A
Rationale: When dealing with seborrheic dermatitis (cradle cap) in infants, it is essential to use a soft brush and gently scrub the affected area to help remove the scales. This process can aid in managing the condition and preventing further build-up. It is important to be gentle to avoid irritating the baby's delicate skin. Choice B is incorrect as gentle scrubbing with a soft brush can help in the removal of scales. Choice C is incorrect because regular but gentle washing is recommended to manage cradle cap. Choice D is incorrect as using specialized shampoos designed for cradle cap is usually recommended over soap and water.
3. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?
- A. International normalized ratio (INR) of 1.0.
- B. Prothrombin time (PT) of 12 seconds.
- C. Partial thromboplastin time (PTT) of 60 seconds.
- D. International normalized ratio (INR) of 2.5.
Correct answer: D
Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.
4. A client is experiencing acute bronchospasm. What is the nurse's priority intervention?
- A. Administer a nebulizer treatment of albuterol.
- B. Start an IV infusion of normal saline.
- C. Administer oxygen at 4L/min via nasal cannula.
- D. Position the client in a high Fowler's position.
Correct answer: A
Rationale: The correct answer is to administer a nebulizer treatment of albuterol. In acute bronchospasm, the priority intervention is to deliver a bronchodilator like albuterol to open the airways and improve breathing. Starting an IV infusion of normal saline (Choice B) may be necessary but not the priority in this situation. Administering oxygen at 4L/min via nasal cannula (Choice C) is important but not the first intervention for bronchospasm. Positioning the client in a high Fowler's position (Choice D) can help with breathing but is not the priority over administering a bronchodilator.
5. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Blood urea nitrogen (BUN) of 40 mg/dl
- C. Serum potassium of 6.0 mEq/L
- D. Serum creatinine of 2.5 mg/dl
Correct answer: C
Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.
