A client was seen in the emergency room with a complaint of severe episodes of vomiting and diarrhea, and complains of feeling lightheaded.
Which laboratory test should the nurse prioritize?

Blood glucose levels.

Serum potassium levels.

Lipid profile.

Thyroid function tests.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Blood glucose levels are important but are not the immediate priority for assessing the cause of severe vomiting and diarrhea with lightheadedness. Electrolyte imbalances are more likely to be the cause.

Choice B rationale

Serum potassium levels should be prioritized as vomiting and diarrhea can lead to significant potassium loss, which can result in dangerous cardiac and neuromuscular symptoms. Assessing potassium levels is crucial in this scenario.

Choice C rationale

Lipid profile is not relevant in the acute assessment of severe vomiting, diarrhea, and lightheadedness. This test is more useful for long-term cardiovascular risk assessment.

Choice D rationale

Thyroid function tests are not immediately relevant to the acute symptoms of vomiting and diarrhea with lightheadedness. Electrolyte imbalances are a more immediate concern.

Correct Answer is A

Explanation

Choice A rationale

Dysuria, or painful urination, is a common symptom of acute cystitis (bladder infection). Clients with acute cystitis often report burning sensations during urination and frequent urges to urinate.

Choice B rationale

Nasal congestion is not a symptom associated with acute cystitis. It is more commonly related to respiratory conditions like colds or allergies.

Choice C rationale

Joint pain is not related to acute cystitis. Joint pain can be associated with various musculoskeletal or autoimmune conditions, but not typically with a bladder infection.

Choice D rationale

Shortness of breath is not a symptom of acute cystitis. This symptom is more relevant to respiratory or cardiovascular conditions, not bladder infections.

A. Use the inhaler before engaging in physical activity. B. Skip doses if symptoms improve. C. Use the inhaler only when experiencing severe symptoms. D. Double the dose if symptoms do not improve immediately.

Correct Answer is A

Explanation

Choice A rationale

Using the inhaler before engaging in physical activity helps to prevent exercise-induced bronchospasm, which is common in patients with COPD.

Choice B rationale

Skipping doses if symptoms improve is not recommended as it can lead to suboptimal control of COPD and potential exacerbations.

Choice C rationale

Using the inhaler only when experiencing severe symptoms is not effective in managing COPD. Regular use as prescribed helps maintain lung function and prevent exacerbations.

Choice D rationale

Doubling the dose if symptoms do not improve immediately is not safe and can lead to adverse effects. Patients should follow the prescribed dosage and consult their healthcare provider if symptoms persist.
