Pharmacology HESI Quizlet
1. A client is diagnosed with pulmonary embolism and is to be treated with streptokinase (Streptase). A nurse would report which priority data collection finding to the registered nurse before initiating this therapy?
- A. Adventitious breath sounds
- B. Temperature of 99.4°F orally
- C. Blood pressure of 198/110 mm Hg
- D. Respiratory rate of 28 breaths/min
Correct answer: C
Rationale: The correct answer is C. Streptokinase therapy is contraindicated in severe uncontrolled hypertension due to the risk of cerebral hemorrhage. A blood pressure of 198/110 mm Hg indicates severe hypertension, which needs to be addressed before initiating streptokinase to prevent potential complications.
2. A female client on a psychiatric unit is sweating profusely while vigorously doing push-ups and then running the length of the corridor several times before crashing into furniture in the sitting room. Picking herself up, she begins to toss chairs aside, looking for a red one to sit in. When another client objects to the disturbance, the client shouts, “I am the boss here. I do what I want.” Which nursing problem best supports these observations?
- A. Deficient diversional activity related to excess energy level.
- B. Disturbed personal identity related to grandiosity.
- C. Risk for activity intolerance related to hyperactivity.
- D. Risk for other-directed violence related to disruptive behaviors.
Correct answer: D
Rationale: The client's behavior of engaging in disruptive and aggressive actions, as well as claiming authority over others in the setting, indicates a risk for other-directed violence. This behavior poses a potential threat to the safety of others in the environment. Choice A is incorrect as the client's behavior is not solely indicative of a lack of diversional activities but rather a more serious issue. Choice B is incorrect as the behavior described does not primarily reflect disturbances in personal identity but rather displays of power and aggression. Choice C is incorrect as the client's actions do not suggest an intolerance to activity but rather an excessive and potentially harmful level of hyperactivity.
3. The nurse is caring for a client with a history of atrial fibrillation who is receiving warfarin (Coumadin). Which laboratory value should be closely monitored?
- A. Serum potassium level
- B. Prothrombin time (PT)
- C. International Normalized Ratio (INR)
- D. Serum sodium level
Correct answer: C
Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation to prevent complications such as bleeding or clotting. Choices A, B, and D are incorrect. While monitoring electrolyte levels like serum potassium and sodium is important in overall client care, they are not specific to monitoring the effects of warfarin therapy. Prothrombin time (PT) is a component of INR and helps in monitoring warfarin therapy, but INR gives a standardized result that is independent of the laboratory method used, making it the preferred choice for monitoring warfarin therapy.
4. A client receiving chemotherapy for cancer treatment is experiencing nausea and vomiting. What is the nurse's best intervention to manage these symptoms?
- A. Offer frequent, small meals
- B. Administer antiemetics before meals
- C. Encourage the client to eat a high-fat diet
- D. Provide the client with cold, carbonated beverages
Correct answer: B
Rationale: Administering antiemetics before meals is the best intervention to manage nausea and vomiting in clients receiving chemotherapy. This proactive approach helps control symptoms by preventing nausea from occurring, rather than waiting to treat it once symptoms have already started. Offering frequent, small meals (choice A) may worsen symptoms in some cases due to increased stomach activity. Encouraging a high-fat diet (choice C) can be difficult for nauseated clients and may not alleviate symptoms. Providing cold, carbonated beverages (choice D) could exacerbate nausea further due to the temperature and carbonation.
5. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which assessment finding should the nurse anticipate?
- A. Oliguria.
- B. Kussmaul respirations.
- C. Fruity odor on the breath.
- D. Blood glucose level of 250 mg/dL.
Correct answer: B
Rationale: Kussmaul respirations (B) are a deep and labored breathing pattern associated with diabetic ketoacidosis (DKA) and are expected in this condition. While oliguria (A), fruity odor on the breath (C), and elevated blood glucose level (D) are also signs of DKA, Kussmaul respirations are more specific and critical to the condition, indicating severe metabolic acidosis.
