Practice HESI Fundamentals Exam
1. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
- A. Monitor serum calcium levels.
- B. Monitor serum potassium levels.
- C. Monitor serum sodium levels.
- D. Monitor serum magnesium levels.
Correct answer: B
Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
2. A client with heart failure is being taught by a nurse on reducing daily sodium intake. Which factor is most crucial in determining the client’s ability to learn new dietary habits?
- A. The client's involvement in planning the change
- B. The cost of the dietary changes
- C. The availability of low-sodium foods
- D. The client’s previous dietary knowledge
Correct answer: D
Rationale: The client’s previous dietary knowledge is the most critical factor in determining the ability to learn new dietary habits. Understanding the client's existing dietary knowledge helps tailor the teaching to build upon what they already know. While client involvement in planning changes can increase adherence and motivation, the foundational knowledge is essential for effective learning. The cost of dietary changes and the availability of low-sodium foods are important considerations but not as crucial as the client's existing knowledge.
3. A healthcare professional is caring for a client with a chest tube. Which observation requires immediate intervention?
- A. Constant bubbling in the suction control chamber
- B. Intermittent bubbling in the water seal chamber
- C. Drainage of 50 ml per hour
- D. Crepitus around the insertion site
Correct answer: D
Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, a serious condition that requires immediate attention. It can be a sign of an air leak in the lung or surrounding tissues. Constant bubbling in the suction control chamber is expected in a functioning chest tube system as it indicates proper suction. Intermittent bubbling in the water seal chamber is also normal, showing that the system is functioning correctly, allowing air to escape but not re-enter. Drainage of 50 ml per hour is within the expected range for chest tube output and does not require immediate intervention unless there are other concerning signs such as rapid increase or a sudden change in color or consistency.
4. When preparing to lift and reposition a patient, which action should the nurse take first?
- A. Assess weight to determine assistance needs.
- B. Position a drawsheet under the patient.
- C. Delegate the task to a nursing assistive personnel.
- D. Attempt to manually lift the patient alone before asking for assistance.
Correct answer: A
Rationale: The first action the nurse should take when preparing to lift and reposition a patient is to assess the patient's weight to determine the assistance needed. This step is crucial for the safety of both the patient and the nurse. Positioning a drawsheet under the patient (Choice B) is important for the comfort and safety during the repositioning process but should come after assessing the weight and assistance requirements. Delegating the task to a nursing assistive personnel (Choice C) can be considered once the assessment is complete and additional help is needed. Attempting to manually lift the patient alone before asking for assistance (Choice D) is unsafe and should never be done without first assessing the weight and determining the need for help.
5. A client with a diagnosis of Guillain-Barre syndrome is in a non-responsive state, yet vital signs are stable and breathing is independent. What should the nurse document to most accurately describe the client's condition?
- A. Comatose, breathing unlabored
- B. Glasgow Coma Scale 8, respirations regular
- C. Appears to be sleeping, vital signs stable
- D. Glasgow Coma Scale 13, no ventilator required
Correct answer: B
Rationale: The correct answer is B. A Glasgow Coma Scale of 8 with regular respirations accurately describes a non-responsive state with independent breathing. Choice A is incorrect because 'comatose' implies a deeper state of unconsciousness than what is described in the scenario. Choice C is inaccurate as the client is not merely sleeping but non-responsive. Choice D is incorrect as a Glasgow Coma Scale of 13 indicates a higher level of consciousness than what is presented in the scenario.
