Evolve HESI Medical Surgical Practice Exam Quizlet
1. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?
- A. Cardiac output.
- B. Right atrial blood flow.
- C. Left end-diastolic pressure.
- D. Cardiac index.
Correct answer: C
Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.
2. What is located on the rough endoplasmic reticulum?
- A. Microvilli
- B. Mitochondria
- C. Lysosomes
- D. Ribosomes
Correct answer: D
Rationale: The rough endoplasmic reticulum is studded with ribosomes, not microvilli, mitochondria, or lysosomes. Ribosomes are responsible for protein synthesis, making them an essential component of the rough endoplasmic reticulum.
3. 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.
4. Nurse Ronn is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome, the nurse would expect to find:
- A. Hypotension.
- B. Thick, coarse skin.
- C. Deposits of adipose tissue in the trunk and dorsocervical area.
- D. Weight gain in arms and legs.
Correct answer: C
Rationale: In Cushing's syndrome, the characteristic features include central obesity with deposits of adipose tissue in the trunk and dorsocervical area, often referred to as a 'buffalo hump.' Hypotension (Choice A) is not typically associated with Cushing's syndrome; instead, hypertension is more common. Thick, coarse skin (Choice B) is seen in conditions like hypothyroidism, not specifically in Cushing's syndrome. Weight gain in the arms and legs (Choice D) is not a typical finding in Cushing's syndrome; rather, weight gain is more prominent in the central areas of the body.
5. A Native American individual presents to the clinic with complaints of frequent abdominal cramping and nausea. They state that they have chronic constipation and have not had a bowel movement in five days, despite trying several home remedies. Which intervention is most important for the healthcare provider to implement?
- A. Evaluate the stool samples for the presence of blood
- B. Assess for the presence of an impaction
- C. Determine which home remedies were used
- D. Obtain a list of prescribed medications
Correct answer: C
Rationale: It is crucial to determine which home remedies the individual has tried to avoid interactions with prescribed treatments and consider cultural practices that may influence their healthcare choices. Understanding the home remedies used can provide insights into the individual's health beliefs, preferences, and potential interactions with conventional treatments, allowing for a more holistic approach to their care.
