Pharmacology HESI 2023 Quizlet
1. A client diagnosed with a sinus infection is prescribed ampicillin sodium. The practical nurse (PN) should instruct the client to notify the healthcare provider immediately if which symptom occurs?
- A. Rash
- B. Nausea
- C. Headache
- D. Dizziness
Correct answer: A
Rationale: The correct answer is A - Rash. Rash is the most common adverse side effect of all generations of penicillin, indicating an allergy to the medication. An allergic reaction could lead to anaphylactic shock, a severe and potentially life-threatening emergency. It is crucial for the client to inform the healthcare provider promptly if a rash develops after taking ampicillin sodium.
2. A homeless person who is in the manic phase of bipolar disorder is admitted to the mental health unit. Which laboratory finding obtained on admission is most important for the nurse to report to the healthcare provider?
- A. Decreased thyroid stimulating hormone level
- B. Elevated liver function profile
- C. Increased white blood cell count
- D. Decreased hematocrit and hemoglobin levels
Correct answer: A
Rationale: The correct answer is A: Decreased thyroid stimulating hormone level. Hyperthyroidism causes an increased level of serum thyroid hormones (T3 and T4), which inhibit the release of TSH. In this case, a decreased TSH level can indicate hyperthyroidism, which can present with manic behavior. Elevated liver function profile (B) is not directly related to the manic phase of bipolar disorder. Increased white blood cell count (C) typically indicates an infection or inflammation, not directly related to the manic phase. Decreased hematocrit and hemoglobin levels (D) may suggest anemia but are not as crucial in the context of a manic phase of bipolar disorder.
3. A client has a new cast on the left arm, and the nurse is assessing the client. Which of the following findings should the nurse report to the provider immediately?
- A. Increased warmth in the affected arm
- B. Itching under the cast
- C. Pain with passive movement
- D. Drainage on the cast
Correct answer: C
Rationale: The correct answer is C: Pain with passive movement. Pain with passive movement in a client with a new cast can indicate compartment syndrome, a serious condition where pressure builds up within the muscles, nerves, and blood vessels of the affected limb, potentially leading to tissue damage. Immediate reporting is crucial to prevent further complications. Increased warmth in the affected arm could be a normal inflammatory response to the injury and casting process. Itching under the cast is common and can be managed without immediate concern. Drainage on the cast may be expected initially after casting due to residual moisture from the setting process, but ongoing or excessive drainage should be monitored and reported if persistent.
4. A client is scheduled for hip surgery in an hour. Which of the following actions is the nurse’s priority?
- A. Ensure that the client signs the consent form.
- B. Lock the client’s valuables in a secure location.
- C. Verify the client’s lab values in the medical record.
- D. Administer the prescribed preoperative sedative.
Correct answer: A
Rationale: The nurse’s priority is to ensure that the client signs the consent form before the hip surgery. This is crucial as it ensures that the client has provided informed consent for the procedure. Locking valuables, verifying lab values, and administering sedatives are important tasks but ensuring consent takes precedence as it directly impacts the client’s right to make decisions about their care.
5. Which disorder is characterized by demyelination of neurons in the central nervous system?
- A. Multiple sclerosis
- B. Parkinson's disease
- C. Alzheimer's disease
- D. Huntington's disease
Correct answer: A
Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.
