Correct Answer: C

Rationale: The correct answer is C: 'health threat.' The new pregnancy poses a health threat due to the potential strain on resources and the existing issues with the children, such as underweight and being pale. Choice A is incorrect as it does not fully capture the potential risks associated with the new pregnancy. Choice B is also incorrect as it includes 'health deficit,' which is not explicitly mentioned in the scenario. Choice D, 'foreseeable crisis,' is not the most fitting description of the situation presented.

Correct Answer: C

Rationale: The correct answer is C, 'Prolonged hypoxemia.' Prolonged hypoxemia is a critical condition that requires specialized pediatric care due to the high risk of cardiac arrest. The other choices, such as congenital cardiac defects, acute febrile illness, and severe multiple trauma, may also require attention, but prolonged hypoxemia poses the highest risk for cardiac arrest and demands specialized expertise in managing pediatric patients with this condition.

Correct Answer: B

Rationale: The correct answer is to inspect the nares and ears for skin breakdown. This is important because the nasal cannula can cause skin breakdown due to prolonged use and friction. Ensuring that the skin is intact helps prevent complications. Choice A is incorrect as oxygen therapy via a nasal cannula does not involve mist. Choice C is incorrect as lubricating the tips of the cannula is not a standard practice and may lead to complications. Choice D is incorrect because while cleanliness is important, maintaining sterile technique is not necessary for handling a nasal cannula in this context.

Correct Answer: A

Rationale: The correct first step for thermal protection of a newborn is to dry the baby thoroughly immediately after birth. This helps prevent heat loss and is crucial in maintaining the baby's body temperature. Choice B, covering the baby with a clean, dry cloth after the cord has been cut, is not the initial step as drying the baby comes first. Choice C, drying the baby thoroughly after the cord has been cut, is also not the first step. Choice D, covering the baby with a clean, dry cloth immediately after birth, is not as effective as drying the baby to prevent heat loss.

Correct Answer: B

Rationale: The correct answer is 'B: researcher.' In this context, the individual is primarily involved in developing research questions, conducting research, and disseminating findings, which aligns with the responsibilities of a researcher. Choice 'A: manager' is incorrect because the role described does not primarily involve managerial duties. Choice 'C: clinician/practitioner' is also incorrect as the focus is on research activities rather than direct clinical practice. Choice 'D: health promotion specialist' does not encompass the full scope of responsibilities described in the scenario.
