HESI Fundamentals Practice Questions
1. When teaching a client how to administer medication through a jejunostomy tube, which of the following instructions should the nurse include?
- A. Flush the tube before and after each medication.
- B. Mix medications with enteral feeding.
- C. Push tablets through the tube slowly.
- D. Mix crushed medications before dissolving them in water.
Correct answer: A
Rationale: The correct answer is to flush the tube before and after each medication administration. This helps prevent clogging and ensures the medication is delivered properly. Mixing medications with enteral feeding (choice B) is incorrect as medications should be administered separately. Pushing tablets through the tube (choice C) is not recommended as they should be properly dissolved before administration. Mixing all crushed medications before dissolving them in water (choice D) is incorrect; medications should be dissolved individually to avoid interactions or inconsistencies in dosages.
2. The nurse is performing a physical assessment on a client with insulin-dependent diabetes mellitus. Which client complaint calls for immediate nursing action?
- A. Diaphoresis and shakiness
- B. Reduced sensation in the lower leg
- C. Intense thirst and hunger
- D. Painful hematoma on thigh
Correct answer: A
Rationale: Diaphoresis and shakiness are classic signs of hypoglycemia in a client with insulin-dependent diabetes mellitus. Hypoglycemia is a medical emergency that requires immediate intervention to prevent further complications. The nurse should address this complaint promptly by providing a fast-acting source of glucose to raise the client's blood sugar levels. Reduced sensation in the lower leg may indicate peripheral neuropathy, which is a common complication of diabetes but does not require immediate action unless there are signs of injury. Intense thirst and hunger are symptoms of hyperglycemia, which also requires intervention but not as urgently as hypoglycemia. A painful hematoma on the thigh may require assessment and management, but it is not as urgent as addressing hypoglycemia.
3. A client tells the nurse that she thinks she's pregnant. Which signs or symptoms provide the best indication that the client is pregnant?
- A. Morning sickness.
- B. Breast tenderness.
- C. Amenorrhea.
- D. Hegar's sign.
Correct answer: D
Rationale: Hegar's sign, which is a softening of the lower uterine segment, is considered a probable sign of pregnancy as it indicates changes in the cervix and uterus that occur during pregnancy. Amenorrhea, the absence of menstruation, is a common early sign of pregnancy but can also be due to other factors. Morning sickness, nausea and vomiting, can be a sign of early pregnancy but is not as specific as Hegar's sign. Breast tenderness is a common symptom in early pregnancy due to hormonal changes, but it is not as definitive as Hegar's sign in indicating pregnancy.
4. The nurse is planning care for a family whose children did not receive childhood immunizations. After one of the children contracted mumps, the father is diagnosed with orchitis. Which intervention should be included in the father's plan of care?
- A. Use of bedrest with scrotal support
- B. Administration of antibiotics for 10 days
- C. Applying heat to promote the healing process
- D. Using an ice pack to reduce scrotal pain
Correct answer: A
Rationale: For orchitis, the recommended intervention is bedrest with scrotal support. This helps reduce swelling and discomfort in the scrotum. Antibiotics are generally not required for viral orchitis, so administering antibiotics for 10 days (Choice B) is not indicated. Applying heat (Choice C) may worsen swelling and should be avoided. Using an ice pack (Choice D) is not the preferred method for managing orchitis; it may not be as effective as providing support and rest for the scrotum.
5. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?
- A. Erythrocyte sedimentation rate
- B. Potassium hydroxide prep
- C. Wound culture
- D. Serum immunoglobulin E (IgE) level
Correct answer: D
Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.
