A chemical reaction between drugs prior to their administration or absorption is known as:
- A. a drug incompatibility
- B. a side effect
- C. an adverse event
- D. an allergic response
Correct Answer: A
Rationale: A drug incompatibility occurs when drugs react chemically before administration, potentially reducing efficacy or causing harm. Side effects and adverse events occur post-administration, and allergic responses are immune-mediated.

During a routine health screening, the nurse should talk to the parents of a 1-year-old child about which of the following?
- A. the potential hazards of accidents
- B. appropriate nutrition now that the child has been weaned from breastfeeding
- C. toilet training
- D. how to prevent accidents in the house
Correct Answer: A
Rationale: During a routine health screening for a 1-year-old child, discussing the potential hazards of accidents is crucial. Accidents are the primary source of injury in children and can be life-threatening. Addressing appropriate nutrition now that the child has been weaned from breastfeeding should have already been discussed. Toilet training is important but is typically addressed at a later age as one year is too early for this milestone. While preventing accidents in the house is important, focusing on the potential hazards of accidents in general is more comprehensive and critical for the child's safety.
How should a nurse listen to the breath sounds of a client?
- A. Ask the client to lie prone.
- B. Ask the client to breathe in and out through the nose.
- C. Hold the bell of the stethoscope lightly against the chest.
- D. Listen for at least one full respiration in each location on the chest.
Correct Answer: D
Rationale: To best listen to breath sounds, the nurse should have the client sit, leaning slightly forward, with arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little deeper than usual, but to stop if feeling dizzy. The nurse should hold the flat diaphragm end piece of the stethoscope firmly against the client's chest wall. It is crucial to listen for at least one full respiration in each location on the chest to assess breath sounds accurately. Side-to-side comparison is essential in breath sound assessment. Therefore, options A, B, and C are incorrect as they do not align with the correct procedure for listening to breath sounds.
The LPN is caring for a 9-month-old infant. Which of these behaviors exhibited by the child warrants further investigation?
- A. She prefers crawling over walking and makes no attempt to walk.
- B. She seems distressed by new adults.
- C. She does not respond to her own name.
- D. She only babbles "mama"? and "dada."?
Correct Answer: C
Rationale: The correct answer is that the child does not respond to her own name. By 9 months, children should be babbling simple words, crawling, and responding to their name. Not responding to one's name can be an early indicator of a potential developmental delay, warranting further investigation. Preferring crawling over walking, being distressed by new adults, and babbling 'mama' and 'dada' are typical behaviors for a 9-month-old and do not necessarily require immediate concern.
Around what age do children typically start to develop 'stranger anxiety'?
- A. 9 months
- B. 6 months
- C. 3 months
- D. 12 months
Correct Answer: B
Rationale: The correct answer is '6 months.' At around this age, children typically start to develop 'stranger anxiety' as they become more aware of unfamiliar faces and may start showing signs of distress or anxiety around strangers. At 3 months, infants are still very young and unlikely to display stranger anxiety. While by 9 or 12 months, children have usually already developed some level of stranger anxiety, it typically starts around 6 months, making it the most appropriate answer in this context.
During the examination of a client's throat, a nurse touches the posterior wall with a tongue blade and elicits the gag reflex. The nurse documents normal function of which cranial nerves?
- A. Cranial nerves V and VI
- B. Cranial nerves XII and VIII
- C. Cranial nerves XII and VIII
- D. Cranial nerves IX and X
Correct Answer: D
Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.
