When providing nursing care to a client receiving oxygen therapy via a nasal cannula, which of the following interventions would be appropriate?

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: C

Rationale: The maternal mortality rate is calculated as 6 maternal deaths per 1000 live births. The correct answer is C because to calculate the maternal mortality rate, you divide the number of maternal deaths by the number of live births and then multiply by 1000. Choices A, B, and D are incorrect as they do not match the given data on maternal deaths and live births for municipality X.

Correct Answer: D

Rationale: The correct answer is D: Elevated creatinine phosphokinase (CPK). Elevated CPK levels indicate muscle damage, including damage to the cardiac muscle, which aligns with the diagnosis of myocardial infarction. Choice A, low serum albumin, is not directly related to myocardial infarction. Choice B, high serum cholesterol, is more associated with conditions like atherosclerosis rather than acute myocardial infarction. Choice C, abnormally low white blood cell count, is typically not a lab value associated with myocardial infarction; instead, it could suggest other conditions like infections or bone marrow issues.

Correct Answer: D

Rationale: The correct answer is D - 'overcrowding and its effect.' While overcrowding is an important topic, it will be given least priority compared to the other choices when conducting health education sessions for a group of mothers. Proper selection and preparation of food (Choice A) is crucial for ensuring adequate nutrition, handwashing before preparing food (Choice B) is essential for preventing foodborne illnesses, and cutting children's fingernails short (Choice C) is important for maintaining good hygiene. Overcrowding, although significant in the context of public health, might be considered less immediately relevant for a group of mothers in a health education session focused on more direct and practical aspects of family health and hygiene.

Correct Answer: B

Rationale: The correct answer is to assess the child's asthma management plan. This is the priority action as it allows the nurse to evaluate the current treatment regimen, identify any gaps or areas for improvement, and ensure that the plan is being effectively implemented. Teaching the child how to use an inhaler (Choice A) may be important but should come after assessing the management plan. Discussing the importance of school attendance with the parents (Choice C) is secondary to ensuring proper asthma management. Referring the child to a pulmonologist (Choice D) may be necessary but is not the priority at this stage; first, the nurse needs to evaluate the current plan in place.

Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. Enalapril, an ACE inhibitor, can lead to hyperkalemia as a side effect. ACE inhibitors can cause potassium retention by inhibiting aldosterone secretion, which may result in elevated potassium levels. Hypoglycemia (choice B) is not typically associated with enalapril use. Hypercalcemia (choice C) is also not a common side effect of enalapril. Hypokalemia (choice D) is the opposite of what is expected with enalapril, as it tends to cause potassium retention.

Correct Answer: A

Rationale: The correct information the nurse should provide is that anthrax infection occurs when spores enter a host. Choice B is incorrect as mature anthrax bacteria do not live dormant on inanimate objects. Choice C is incorrect as anthrax spores can survive for extended periods outside a living host. Choice D is incorrect as anthrax is not transmitted by respiratory droplets from person to person.

Correct Answer: C

Rationale: Hyperoxygenating the client before and after suctioning helps prevent hypoxia by ensuring adequate oxygen levels during the procedure, which briefly interrupts the client's normal breathing pattern. Choice A is incorrect because inserting a fenestrated catheter with a whistle tip without suction would not prevent hypoxia. Choice B is incorrect as completing the suction pass in 30 seconds with a pressure of 150 mm Hg may lead to hypoxia. Choice D is incorrect as minimizing the suction pass to 60 seconds may not provide enough time for effective suctioning and could lead to hypoxia.

Correct Answer: A

Rationale: A community hospital is categorized under secondary level health care. Secondary level health care facilities, like community hospitals, provide specialized outpatient care, diagnostic services, and treatment that are more complex than what is offered in primary health care settings. Choice B, primary health care, refers to basic and routine health care services typically provided by family doctors or general practitioners, which is not the level of care provided by community hospitals. Tertiary level care (choice C) involves highly specialized and complex medical services such as neurosurgery or organ transplants, which are beyond the scope of services provided by community hospitals. Intermediate level care (choice D) is not a recognized category in the hierarchy of health care levels.
