HESI RN
HESI Fundamentals
1. When a client has suffered severe burns all over his body, the most effective method of monitoring the cardiovascular system is:
- A. Cuff blood pressure.
- B. Arterial pressure.
- C. Pulmonary artery pressure.
- D. Central venous pressure.
Correct answer: D
Rationale: Central venous pressure (CVP) monitoring is the most effective method to assess fluid status and the cardiovascular system in a client with severe burns. Severe burns can lead to significant fluid shifts and hemodynamic changes, making central venous pressure monitoring crucial for guiding fluid resuscitation and managing cardiovascular stability in these patients.
2. What information should be reinforced with the mother of a child with ringworm (Tinea)?
- A. Ringworm is not contagious.
- B. Tinea infections are indicative of poor hygiene and uncleanliness.
- C. Tinea infections are spread by direct and indirect contact.
- D. Ringworm often subsides spontaneously.
Correct answer: C
Rationale: The correct answer is C. Ringworm, a fungal infection, is highly contagious and can be spread by direct contact with infected individuals or animals and indirectly through contaminated objects. It is important for the mother to understand the modes of transmission to prevent the spread of the infection to others and to take necessary precautions to ensure proper treatment and containment of the condition. Choices A and D are incorrect because ringworm is indeed contagious, and it may not always subside spontaneously. Choice B is misleading as tinea infections are not solely indicative of poor hygiene; they can affect anyone, regardless of personal cleanliness.
3. A nurse is reviewing the medication list for a client with heart failure. Which medication should the nurse question?
- A. Furosemide
- B. Digoxin
- C. Ibuprofen
- D. Carvedilol
Correct answer: C
Rationale: The correct answer is C: Ibuprofen. Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), can cause fluid retention, which may worsen heart failure symptoms. It should be used with caution or avoided in clients with heart failure. Furosemide (choice A) is a diuretic commonly used in heart failure to reduce fluid overload. Digoxin (choice B) is a medication that helps the heart beat stronger and slower, often used in heart failure. Carvedilol (choice D) is a beta-blocker that is beneficial in heart failure management. Therefore, Ibuprofen is the medication that the nurse should question in this scenario.
4. Which laboratory test should the nurse monitor to determine the effectiveness of heparin therapy for a client with deep vein thrombosis?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Activated partial thromboplastin time (aPTT)
- D. Hemoglobin and hematocrit
Correct answer: C
Rationale: The activated partial thromboplastin time (aPTT) is the specific laboratory test used to monitor the effectiveness of heparin therapy in patients with deep vein thrombosis. It measures the time it takes for blood to clot and is crucial in assessing the therapeutic range of heparin. Platelet count, prothrombin time (PT), and hemoglobin and hematocrit levels are important parameters in assessing coagulation and blood status but do not directly indicate the effectiveness of heparin therapy.
5. The nurse is preparing to begin a medication regimen for a patient who will receive intravenous ampicillin and gentamicin. Which is an important nursing action?
- A. Administer each antibiotic to infuse over 15 to 20 minutes.
- B. Order serum peak and trough levels of ampicillin.
- C. Prepare the schedule so that the drugs are given at the same time.
- D. Set up separate tubing sets for each drug labeled with the drug name and date.
Correct answer: D
Rationale: When administering intravenous aminoglycosides like gentamicin with penicillins such as ampicillin, it is crucial to avoid mixing them in the same container. Separate tubing sets labeled with the drug name and date should be used to prevent interactions between the medications. Administering each antibiotic over 15 to 20 minutes (Choice A) may not be appropriate for all medications and does not address the issue of compatibility. Ordering serum peak and trough levels of ampicillin (Choice B) is important for monitoring drug levels but does not directly address the administration process. Preparing a schedule to give drugs simultaneously (Choice C) may increase the risk of drug interactions and is not recommended when administering incompatible medications.
