Which of the following terms indicates that the patient has a hearing loss caused by aging?
- A. Otoplasty
- B. Presbycusis
- C. Otalgia
- D. Tinnitus
Correct Answer: B
Rationale: The correct answer is B: Presbycusis. Presbycusis refers to age-related hearing loss, commonly affecting higher frequencies. As people age, changes in the inner ear structures can lead to hearing loss. Otoplasty (A) is a surgical procedure to correct ear deformities, not related to aging. Otalgia (C) refers to ear pain, not specifically related to aging. Tinnitus (D) is the perception of ringing or buzzing in the ears, which can occur at any age and is not exclusive to age-related hearing loss.

Which of the following lab value profiles should the nurse know to be consistent with hemolytic anemia?
- A. Increased RBC, decreased bilirubin, decreased Hgb and Hct, increased reticulocytes
- B. Decreased RBC, increased bilirubin, decreased Hgb and Hct, increased reticulocytes
- C. Decreased RBC, decreased bilirubin, increased Hgb and Hct, decreased reticulocytes
- D. Increased RBC, increased bilirubin, increased Hgb and Hct, decreased reticulocytes
Correct Answer: A
Rationale: Step-by-step rationale for the correct answer (A):
1. Increased RBC: Hemolytic anemia leads to increased RBC production as the body compensates for the destruction of red blood cells.
2. Decreased bilirubin: Bilirubin levels decrease due to the accelerated breakdown of red blood cells.
3. Decreased Hgb and Hct: Hemolysis causes a decrease in hemoglobin and hematocrit levels as red blood cells are destroyed.
4. Increased reticulocytes: Reticulocytes are immature red blood cells released by the bone marrow in response to increased RBC destruction.
Summary:
- Choice B is incorrect as hemolytic anemia would lead to increased, not decreased, bilirubin levels.
- Choice C is incorrect as hemolytic anemia would lead to decreased, not increased, Hgb and Hct levels.
- Choice D is incorrect as hemolytic anemia would not lead to increased levels of all parameters
The lungs regulate acid-base balance b₃y⁻ all of the following except:
- A. Excreting HCO into the blood
- B. Controlling carbon dioxide levels
- C. Slowing ventilation
- D. Increasing ventilation
Correct Answer: C
Rationale: The correct answer is C: Slowing ventilation. The lungs regulate acid-base balance by controlling carbon dioxide levels through ventilation. Increasing ventilation helps expel excess carbon dioxide, thus regulating pH. Slowing ventilation would lead to CO2 buildup and an imbalance in acid-base levels. Excreting HCO3- into the blood (choice A) helps maintain pH, while increasing ventilation (choice D) aids in removing excess CO2. Therefore, slowing ventilation is the exception as it would disrupt the acid-base balance by not effectively regulating carbon dioxide levels.
The nurse is caring for a patient with HIV who has diarrhea. Which of the following would be most therapeutic to teach the patient to avoid in the diet to reduce diarrhea?
- A. Potassium-rich food
- B. Liquid nutritional supplements
- C. Raw fruits and vegetables
- D. Frozen products
Correct Answer: C
Rationale: The correct answer is C: Raw fruits and vegetables. Patients with HIV and diarrhea should avoid raw fruits and vegetables due to their high fiber content, which can exacerbate diarrhea symptoms. Fiber can increase bowel movements and worsen diarrhea. Therefore, avoiding raw fruits and vegetables can help reduce diarrhea.
Choice A (Potassium-rich food) is not the best answer because potassium-rich foods are important for patients with HIV to maintain electrolyte balance. Choice B (Liquid nutritional supplements) can actually be beneficial in providing essential nutrients to patients with HIV. Choice D (Frozen products) is not directly related to diarrhea management in patients with HIV.
The best way to tell whether or not a patient is breathing, is for the nurse to watch the movement of the:
- A. Extremities
- B. Head
- C. Eyeball
- D. Chest and nostrils A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET L
Correct Answer: D
Rationale: The correct answer is D, "Chest and nostrils." This is because observing the movement of the chest and nostrils is the most reliable way to determine if a patient is breathing. The chest rises and falls with each breath, and the nostrils may flare or move as air is inhaled and exhaled. Monitoring these areas provides a direct indication of respiratory effort. Choices A, B, and C are incorrect because they do not directly reflect the act of breathing. Extremities, head, and eyeball movements are not reliable indicators of breathing function.
Mr. Reyes has a possible skull fracture. The nurse should:
- A. Observe him for signs of Brain injury
- B. Check for hemorrhaging from the oral cavity
- C. Elevate the foot of the bed if he develops symptoms of shock
- D. Observe for symptoms of decreased intracranial pressure and temperature
Correct Answer: A
Rationale: The correct answer is A because observing for signs of brain injury is crucial in assessing a possible skull fracture. Signs may include altered mental status, headache, nausea, vomiting, and unequal pupil size. Choice B is incorrect as hemorrhaging from the oral cavity may not always be present in skull fractures. Choice C is incorrect as elevating the foot of the bed is not recommended for a possible skull fracture. Choice D is incorrect as decreased intracranial pressure and temperature are not typical symptoms of a skull fracture.
