HESI 799 RN Exit Exam Quizlet
1. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?
- A. Low bioavailability
- B. Rapid onset of action
- C. Short half-life
- D. Narrow therapeutic index
Correct answer: D
Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
2. A client with urticaria due to environmental allergies is taking diphenhydramine. Which complaint should the nurse identify as a side effect of the OTC medication?
- A. Nausea and indigestion.
- B. Hypersalivation.
- C. Eyelid and facial twitching.
- D. Increased appetite.
Correct answer: A
Rationale: The correct answer is A: Nausea and indigestion. Diphenhydramine, an antihistamine, commonly causes gastrointestinal side effects such as nausea and indigestion. This medication can have anticholinergic effects, leading to these symptoms. Choices B, C, and D are incorrect because hypersalivation, eyelid and facial twitching, and increased appetite are not typically associated with diphenhydramine use.
3. One day after abdominal surgery, an obese client complains of pain and heaviness in the right calf. What action should the nurse implement?
- A. Observe for unilateral swelling
- B. Administer pain medication
- C. Elevate the leg and apply a warm compress
- D. Notify the healthcare provider
Correct answer: A
Rationale: The correct action for the nurse to implement is to observe for unilateral swelling. Unilateral swelling could indicate a deep vein thrombosis (DVT), which is a serious complication that requires immediate assessment. Administering pain medication or applying warm compress may not address the underlying cause of the symptoms. Notifying the healthcare provider should be done after assessing and identifying the issue of unilateral swelling.
4. The nurse is caring for a client with a chest tube in place following a pneumothorax. Which assessment finding requires immediate intervention?
- A. Oxygen saturation of 94%
- B. Crepitus around the insertion site
- C. Subcutaneous emphysema
- D. Blood pressure of 110/70 mmHg
Correct answer: C
Rationale: Subcutaneous emphysema is the assessment finding that requires immediate intervention in a client with a chest tube following a pneumothorax. Subcutaneous emphysema can indicate a pneumothorax recurrence or air leak, which can compromise respiratory function and lead to serious complications. Oxygen saturation of 94% may be concerning but does not require immediate intervention as it is still within an acceptable range. Crepitus around the insertion site is common after chest tube placement and may not always indicate a problem. A blood pressure of 110/70 mmHg is within normal limits and does not require immediate intervention in this context.
5. A client who developed syndrome of inappropriate antidiuretic hormone (SIADH) associated with small carcinoma of the lung is preparing for discharge. When teaching the client about self-management with demeclocycline (Declomycin), the nurse should instruct the client to report which condition to the healthcare provider?
- A. Insomnia
- B. Muscle cramping
- C. Increased appetite
- D. Anxiety
Correct answer: B
Rationale: The correct answer is B: Muscle cramping. SIADH causes dilutional hyponatremia due to increased ADH release. Demeclocycline is used to block the action of ADH. Muscle cramping can indicate electrolyte imbalances related to hyponatremia, which should be reported to the healthcare provider. Insomnia, increased appetite, and anxiety are not typically associated with the side effects or complications of demeclocycline or SIADH.
