HESI Fundamental Practice Exam
1. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?
- A. Serum creatinine of 3.0 mg/dL
- B. Blood urea nitrogen (BUN) of 45 mg/dL
- C. Serum potassium of 6.5 mEq/L
- D. Hemoglobin of 10 g/dL
Correct answer: C
Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.
2. A community health nurse is caring for a group of families. The nurse should identify which of the following families is experiencing a maturational loss?
- A. A family whose only child recently died due to cancer.
- B. A family whose head of household lost her job.
- C. A family whose house was destroyed in a fire.
- D. A family whose oldest child is moving away for college.
Correct answer: D
Rationale: The correct answer is D because maturational loss is related to developmental changes, such as children leaving for college. This type of loss is tied to the normal life transitions of individuals and can lead to feelings of grief and adjustment. Choices A, B, and C represent different types of losses. Choice A involves a traumatic loss of a child due to illness, choice B involves a financial loss impacting the head of household's job, and choice C involves a material loss due to a fire incident. While these losses are significant, they do not specifically relate to maturational loss, which is associated with expected life stage transitions.
3. The healthcare provider is caring for a client with tuberculosis (TB). Which type of isolation precautions should the healthcare provider implement?
- A. Droplet precautions
- B. Airborne precautions
- C. Contact precautions
- D. Standard precautions
Correct answer: B
Rationale: When caring for a client with tuberculosis (TB), airborne precautions should be implemented. Tuberculosis is spread through the air via droplet nuclei, requiring the use of airborne precautions to prevent the transmission of the infection. Droplet precautions are used for diseases spread by large respiratory droplets, such as influenza or pertussis. Contact precautions are used for diseases that spread through direct contact, such as MRSA. Standard precautions are used for all clients to prevent the transmission of infections from blood, body fluids, non-intact skin, and mucous membranes.
4. 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.
5. A nurse is providing care to four clients. Which of the following situations requires the nurse to complete an incident report?
- A. A nurse tied a client's restraints straps to the moveable part of the bed frame.
- B. An assistive personnel placed a surgical mask on a client who has TB before transporting her to radiology.
- C. A nurse administered a medication to a client 30 minutes before the dose is due.
- D. A client who has an IV infusion pump receives an additional 250 mL of IV fluid.
Correct answer: C
Rationale: The correct answer is C. An incident report should be completed when a nurse administers medication to a client significantly earlier than the scheduled time. This deviation from the prescribed schedule could potentially impact the client's treatment plan and requires documentation for proper evaluation and follow-up. Choices A, B, and D do not necessarily require an incident report. Choice A involves improper restraint application, which is a safety issue but does not directly involve medication administration. Choice B involves a protective measure for a client with TB, which is within the scope of practice for assistive personnel. Choice D describes an increase in IV fluid administration, which may need monitoring but does not necessarily indicate a need for an incident report unless there are specific complications or adverse effects related to the additional fluid.
