Correct Answer: B

Rationale: By 12 months of age, children should have received vaccines for diphtheria, pertussis, polio, and tetanus (DTaP and IPV). The correct answer is B as it includes these vaccines that are typically administered in the first year of life. Measles, mumps, and rubella (MMR) vaccination usually begins at 12 months of age but is not expected to be completed by this time. Choices A and C are incorrect as they include diseases that are not part of the routine immunization schedule for a 12-month-old child.

Correct Answer: D

Rationale: The correct answer is to instruct the postpartum client to call the physician if their vaginal discharge becomes bright red. The vaginal discharge after birth is called lochia, and a return to red or containing clots could indicate impending hemorrhage or infection, necessitating notification of the physician. Choice A is incorrect because although some tenderness may be expected, redness and fatigue are clinical manifestations of mastitis, not normal postpartum changes. Choice B is also incorrect as increased frequency of urination after vaginal delivery could indicate a urinary tract infection, not a normal postpartum change. Choice C is incorrect because running a low-grade temperature for a few days is not expected postpartum; an elevated temperature above 100°F should be reported to the physician as it could indicate infection.

Correct Answer: A

Rationale: In this scenario, the client is experiencing respiratory depression due to opiate overdose. Naloxone (Narcan) is an opioid antagonist that can rapidly reverse the effects of opiates by competitively binding to opioid receptors and displacing the opiates. This action can restore normal respiration and consciousness. Labetalol (Normodyne) is a non-selective beta-blocker used to manage hypertension, not opioid-induced respiratory depression. Neostigmine (Prostigmin) is a cholinesterase inhibitor used to reverse neuromuscular blockade, not opioid overdose. Thiothixene (Navane) is an antipsychotic medication used to manage psychotic disorders, not opioid toxicity.

Correct Answer: C

Rationale: The correct answer is C: 'says 'Mine!' when playing with toys.' At the age of 2, children are in the stage of parallel play and are possessive of their belongings, hence saying 'Mine!' is an age-appropriate behavior. Building towers with blocks (choice A) involves more advanced motor skills and cognitive abilities, which are beyond what most 2-year-olds can do. Trying to color within the lines (choice B) requires fine motor skills that are typically not developed at age 2. Jumping rope (choice D) involves coordination and balance that are beyond the capabilities of a 2-year-old child.

Correct Answer: C

Rationale: The correct answer is C: Trigeminal nerve. To test the motor function of the trigeminal nerve (cranial nerve V), the nurse assesses the muscles of mastication by asking the client to clench their teeth. By trying to separate the client's jaws, the nurse evaluates the strength of the temporal and masseter muscles innervated by the trigeminal nerve. This technique helps assess if the trigeminal nerve is functioning properly. Choices A, B, and D are incorrect because they relate to other cranial nerves that are not involved in the specific motor function being tested in this scenario. These nerves are usually assessed through different examinations such as assessing the pupils and extraocular movements, which are not part of the jaw clenching and opening technique described in the question.
