Correct Answer: C

Rationale: The correct answer is C: Continue taking estrogen as prescribed by your physician. Medications such as estrogen supplements may actually trigger a migraine headache attack. Fluctuations in estrogen, such as before or during menstrual periods, pregnancy, and menopause, seem to trigger headaches in many women. Choices A and B are important to include in the teaching plan for a patient with migraines as avoiding foods containing tyramine and certain drugs can help prevent migraine triggers. Choice D is also relevant as it is essential for the patient to be aware of potential side effects of medications, including rebound headaches.

Correct Answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

Correct Answer: C

Rationale: The correct answer is C. The evaluation stage of the nursing process involves reviewing the assessments, diagnoses, and interventions given to the client and then determining if the client is meeting expected outcomes. In this scenario, the nurse is assessing whether the client is meeting the outcomes set for their care plan and making revisions as needed. Choice A is incorrect as assigning a nursing diagnosis is part of the nursing diagnosis phase, not the evaluation phase. Choice B represents the assessment phase of the nursing process, not the evaluation phase. Choice D involves discussing the client's health history, which is more aligned with the assessment phase rather than the evaluation phase.

Correct Answer: C

Rationale: The most critical aspect of toilet training is the overall mental and physical abilities of the child. While age can play a role, it is not the sole determining factor. Understanding instructions is important but may not be the most critical aspect. Consistent attempts with positive reinforcement can be helpful, but without considering the child's abilities, it may not lead to successful potty training.

Correct Answer: B

Rationale: The correct answer is, "I should exercise until I am exhausted."? This statement indicates a need for further teaching because patients with multiple sclerosis should avoid exercising to the point of exhaustion or fatigue. Strenuous physical activity can increase body temperature and potentially worsen symptoms in individuals with multiple sclerosis. Choice A is correct because lifting weights and resistance training can be appropriate exercises for patients with multiple sclerosis. Choice C is valid because aerobic exercises can also be beneficial. Choice D is accurate as proper stretching before starting an exercise routine is essential for preventing injuries.
