A female client must take streptomycin for tuberculosis. Before therapy begins, the nurse should instruct the client to notify the physician if a health concern occurs?
- A. Impaired color discrimination
- B. Increased urinary frequency
- C. Decreased hearing acuity
- D. Increased appetite
Correct Answer: C
Rationale: The correct answer is C: Decreased hearing acuity. Streptomycin is known to cause ototoxicity, which can lead to decreased hearing acuity. Therefore, the nurse should instruct the client to notify the physician if any changes in hearing occur to prevent permanent hearing loss. Impaired color discrimination (A) and increased appetite (D) are not commonly associated with streptomycin use. Increased urinary frequency (B) is not a typical side effect of streptomycin and would not require immediate physician notification.

Plastron is the air bubble carrying respiratory air in the abdomen of
- A. Belostoma
- B. Nepa (Water boat man)
- C. Chironomous
- D. Mosquito
Correct Answer: B
Rationale: The correct answer is B: Nepa (Water boat man). Plastron is an air bubble that aquatic insects such as Nepa carry to respire underwater. Belostoma and Chironomous do not have plastrons. Mosquitoes breathe through a siphon, not a plastron. Therefore, the correct answer is B.
After receiving a change-of-shift report on four patients admitted to a heart failure unit ,which patient should the nurse assess first?
- A. A patient who reported dizziness after receiving the first dose of captopril.
- B. A patient who has new-onset confusion and restlessness and cool clammy skin.
- C. A patient who is receiving IV nesiritide (Natrecor)
- D. A patient who is receiving oxygen and has crackles bilaterally in the lung bases.
Correct Answer: B
Rationale: The correct answer is B because new-onset confusion, restlessness, and cool clammy skin are signs of poor perfusion and potential deterioration. The nurse should assess this patient first to address possible acute changes in condition. Option A, dizziness after captopril, can be important but not immediately life-threatening. Option C receiving IV nesiritide is stable and monitored closely. Option D with oxygen and crackles indicates pulmonary congestion but is not an immediate priority compared to the signs of poor perfusion in option B.
Which of the following nursing interventions regarding nutrition is used until the suture line heals, usually 10 to 14 days postoperatively?
- A. Enteral feedings
- B. Meticulous mouth care every 4 hours
- C. Gradual advancement of the diet
- D. Reassurance that the sense of taste will return
Correct Answer: A
Rationale: The correct answer is A. Enteral feedings bypass the oral route, allowing the suture line to heal without strain. B (meticulous mouth care) is important but not directly related to nutrition. C (gradual advancement of the diet) occurs later. D (reassurance) addresses psychological concerns but not nutritional needs.
Branches of bronchial tree
- A. primary bronchi_trachea_secondary bronchi_tertiary_bronchioles_terminal
- B. trachea-pri bronchi-sec bronchi-ter bronchi-bronchioles-terinnal
- C. Both a and b
- D. itis
Correct Answer: B
Rationale: The correct answer is B because it correctly lists the branches of the bronchial tree in order: trachea-primary bronchi-secondary bronchi-tertiary bronchi-bronchioles-terminal. The trachea divides into the primary bronchi, which further divide into secondary bronchi, followed by tertiary bronchi, bronchioles, and finally terminal bronchioles. Choice A is incorrect because it lists "primary bronchi_trachea" which is out of order and "tertiary_bronchioles" instead of "tertiary bronchi." Choice C is incorrect because it combines the incorrect order of branches from both A and B. Choice D, "itis," is not a valid term related to the branches of the bronchial tree.
Which of the following structures separates the lung into lobes?
- A. mediastinum
- B. fissure
- C. root
- D. pleura
Correct Answer: B
Rationale: The correct answer is B: fissure. A fissure is a deep groove or division that separates the lung into lobes. Each lung has fissures that divide it into lobes: the right lung has an oblique fissure and a horizontal fissure, while the left lung has an oblique fissure. The mediastinum (A) is the central compartment of the thoracic cavity. The root (C) is the area where structures such as blood vessels and bronchi enter or exit the lung. The pleura (D) is a membrane that covers the lungs but does not separate them into lobes.
