HESI Medical Surgical Practice Exam Quizlet
1. In a client with congestive heart failure, the nurse would be correct in withholding a dose of digoxin without specific instruction from the healthcare provider if the client's
- A. serum digoxin level is 1.5 ng/mL.
- B. blood pressure is 104/68 mmHg.
- C. serum potassium level is 3 mEq/L.
- D. apical pulse is 68/min.
Correct answer: C
Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.
2. A client with a spinal cord injury is admitted to the ICU. Which nursing intervention is most important to include in this client's plan of care?
- A. Monitor for signs of autonomic dysreflexia.
- B. Implement measures to prevent pressure ulcers.
- C. Perform passive range of motion exercises.
- D. Ensure that the client is turned every two hours.
Correct answer: A
Rationale: The correct answer is A: Monitor for signs of autonomic dysreflexia. Autonomic dysreflexia is a life-threatening condition that can occur in clients with spinal cord injuries, especially those with injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure, pounding headache, profuse sweating, and flushing above the level of injury. Failure to recognize and treat autonomic dysreflexia promptly can lead to seizures, stroke, or even death. Therefore, monitoring for signs of autonomic dysreflexia is crucial in clients with spinal cord injuries. Choices B, C, and D are important interventions too, but in the context of a spinal cord injury, monitoring for autonomic dysreflexia takes priority due to its potentially life-threatening nature.
3. A client receiving IV heparin reports tarry stools and abdominal pain. What interventions should the nurse implement?
- A. Prepare to administer warfarin.
- B. Assess the characteristics of the client's pain.
- C. Obtain recent partial thromboplastin time results.
- D. Monitor stool for the presence of blood.
Correct answer: D
Rationale: The correct intervention for the client receiving IV heparin who reports tarry stools and abdominal pain is to monitor the stool for the presence of blood. This is crucial to assess for gastrointestinal bleeding, a potential complication of heparin therapy. Assessing the characteristics of the client's pain may be helpful but is not the priority when signs of GI bleeding are present. Administering warfarin is not appropriate without a thorough assessment and confirmation of the cause of symptoms. While obtaining recent partial thromboplastin time results is important in monitoring heparin therapy, in this scenario, the immediate concern is to assess for possible GI bleeding.
4. A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?
- A. Metabolic acidosis
- B. Respiratory acidosis
- C. Respiratory alkalosis
- D. Metabolic alkalosis
Correct answer: C
Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.
5. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which assessment finding requires immediate intervention?
- A. Use of accessory muscles
- B. Oxygen saturation of 90%
- C. Respiratory rate of 24 breaths per minute
- D. Blood pressure of 110/70 mmHg
Correct answer: A
Rationale: The correct answer is A: Use of accessory muscles. This finding indicates increased work of breathing in a client with COPD and may signal respiratory failure, requiring immediate intervention. In COPD, the use of accessory muscles suggests that the client is in distress and struggling to breathe effectively. Oxygen saturation of 90% is within an acceptable range for a client with COPD receiving supplemental oxygen and does not require immediate intervention. A respiratory rate of 24 breaths per minute is slightly elevated but not a critical finding. A blood pressure of 110/70 mmHg is within the normal range for an adult and does not indicate a need for immediate intervention in this scenario.
