Medical Surgical Assignment Exam HESI
1. What is the major criterion for diagnosing cognitive impairment in a child?
- A. An IQ of 75 or less
- B. Subaverage functioning
- C. An IQ of 70 or less
- D. Onset before 18
Correct answer: C
Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.
2. A client who has a history of unstable angina is admitted to the emergency department with chest pain.
- A. Chest pain relieved by rest.
- B. Chest pain unrelieved after taking 3 sequential nitroglycerin tablets.
- C. Chest pain occurring only with exertion.
- D. Chest pain lasting less than 5 minutes.
Correct answer: B
Rationale: Chest pain unrelieved after taking 3 sequential nitroglycerin tablets indicates a possible myocardial infarction and requires immediate medical attention.
3. A male client with acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia has a CD4+ T cell count of 200 cells/microliter. The client asks the nurse why he keeps getting these massive infections. Which pathophysiologic mechanism should the nurse describe in response to the client's question?
- A. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms.
- B. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.
- C. The humoral immune response lacks B cells that form antibodies and opportunistic infections result.
- D. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages.
Correct answer: D
Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.
4. An older adult woman with a long history of COPD is admitted with progressive shortness of breath and a persistent cough, is anxious, and is complaining of dry mouth. Which intervention should the nurse implement?
- A. Administer a prescribed sedative
- B. Encourage client to drink water
- C. Apply a high flow venturi mask
- D. Assist her to an upright position
Correct answer: D
Rationale: Assisting the client to an upright position is the most appropriate intervention in this situation. Placing the client upright helps improve lung expansion by reducing diaphragmatic pressure, facilitating better air exchange, and increasing oxygenation. This position also aids in easing breathing efforts. Administering a sedative (Choice A) may further depress the respiratory system, worsening the breathing problem. Encouraging the client to drink water (Choice B) may not directly address the respiratory distress caused by COPD. Applying a high flow venturi mask (Choice C) may be beneficial in some cases but assisting the client to an upright position should be the priority to optimize respiratory function.
5. An overweight, young adult male who was recently diagnosed with type 2 diabetes mellitus is admitted for a hernia repair. He tells the nurse that he is feeling very weak and jittery. Which actions should the nurse implement? (Select all that apply)
- A. Check his fingerstick glucose
- B. Assess his skin temperature and moisture
- C. Measure his pulse and BP
- D. All of the Above
Correct answer: D
Rationale: In this scenario, the patient is a young adult male with type 2 diabetes mellitus admitted for a hernia repair who is experiencing weakness and jitteriness. Checking his fingerstick glucose is crucial to assess his blood sugar levels, which can directly impact his symptoms. Assessing his skin temperature and moisture is important to evaluate his peripheral circulation and hydration status. Measuring his pulse and blood pressure helps in gauging his cardiovascular status. Therefore, all the actions mentioned in choices A, B, and C are appropriate for the nurse to implement in this situation to identify the underlying cause of the patient's symptoms. Choice D, 'All of the Above,' is the correct answer because all these actions are necessary for a comprehensive assessment of the patient's condition. Choices A, B, and C are incorrect individually as they each address different aspects of the patient's condition, and a holistic approach is needed to provide optimal care in this situation.
