Medical Surgical Assignment Exam HESI
1. An adolescent female asks the nurse about taking retinoic acid (Accutane). What guidance should be provided by the nurse?
- A. The medication should be used for 10 weeks only.
- B. The medication requires that sexually active females use contraception.
- C. The medication lowers hemoglobin levels very quickly.
- D. The medication has few side effects.
Correct answer: B
Rationale: The correct guidance the nurse should provide is that sexually active females must use contraception while taking Accutane and for 1 month after the 20 weeks it is prescribed. Choice A is incorrect because Accutane is typically taken for a longer duration than 10 weeks. Choice C is incorrect because Accutane does not lower hemoglobin levels quickly. Choice D is incorrect as Accutane is known for having many side effects, including the risk of birth defects.
2. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?
- A. Bilateral crackles in the lung bases.
- B. Low-pressure indicator alarm.
- C. Oxygen saturation of 91%.
- D. Respiratory rate of 18 breaths/minute.
Correct answer: B
Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.
3. While changing the dressing of a client with a leg ulcer, the nurse observes a red, tender, and swollen wound at the site of the lesion. Before reporting this finding to the healthcare provider, the nurse should note which of the client’s laboratory values?
- A. Neutrophil count.
- B. Hematocrit.
- C. Blood pH.
- D. Serum potassium and sodium.
Correct answer: A
Rationale: The correct answer is A: Neutrophil count. Neutrophil count helps assess for infection, which is indicated by the redness, tenderness, and swelling of the wound. Elevated neutrophil count is a common sign of bacterial infection. Hematocrit (choice B) measures the proportion of blood volume that is occupied by red blood cells and is not directly related to wound infection. Blood pH (choice C) and serum potassium and sodium (choice D) are important for assessing acid-base balance and electrolyte levels but are not the primary indicators of wound infection.
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. Which statement correctly explains the etiology of Down syndrome?
- A. There is an extra chromosome on the 21st pair.
- B. There is a missing chromosome on the 21st pair.
- C. There are two pairs of the 21st chromosome.
- D. The 21st chromosome pair is missing.
Correct answer: A
Rationale: The correct answer is A: 'There is an extra chromosome on the 21st pair.' Down syndrome is caused by the presence of an extra copy of chromosome 21, known as trisomy 21. This additional genetic material leads to the characteristics associated with Down syndrome. Choices B, C, and D are incorrect because Down syndrome is not due to a missing chromosome or having two pairs of the 21st chromosome; it results from the presence of an extra chromosome on the 21st pair.
