A client is started on furosemide 80 mg every morning.
Which lab result needs to be reported to the health care provider?
Sodium is 144.
Potassium is 3.0.
Chloride is 99.
Calcium is 5.0.
The Correct Answer is B
Potassium is 3.0.
This is because furosemide is a loop diuretic that can cause hypokalemia (low potassium levels) as a side effect. Hypokalemia can lead to muscle weakness, cramps, cardiac arrhythmias, and digoxin toxicity. The normal range for potassium is 3.5 to 5.0 mEq/L.
Choice A is wrong because sodium is 144 is within the normal range of 135 to 145 mEq/L.
Choice C is wrong because chloride is 99 is within the normal range of 98 to 106 mEq/L.
Choice D is wrong because calcium is 5.0 is within the normal range of 4.5 to 5.5 mg/dL.

Correct Answer is B
Explanation
Notify the health care provider. The nurse should take this action first because the provider can prescribe appropriate interventions to prevent or minimize harm to the client.
The nurse should also inform the unit supervisor, document the error in the client’s medical record, and record the error on the appropriate quality improvement report, but these are not the priority actions.
Choice A is wrong because informing the unit supervisor is not the most urgent action. The supervisor can provide support and guidance to the nurse, but cannot prescribe interventions for the client.
Choice C is wrong because documenting the error in the client’s medical record is not the most urgent action.
The nurse should document the error after notifying the provider and assessing the client. Documentation should include the medication name, dose, route, time, client’s response, and actions taken.
Choice D is wrong because recording the error on the appropriate quality improvement report is not the most urgent action.
The nurse should record the error after notifying the provider and assessing the client. The report should include a factual description of what happened and what was done.
Correct Answer is A
Explanation
Schizophrenia is a disorder that has genetic risk factors, but is not caused by a single gene. The risk of developing schizophrenia is higher if you have a close relative with the disorder, but it is not certain. The risk varies depending on the degree of relatedness and the number of genes involved. The heritability of schizophrenia, which measures how much of the risk is due to genetic factors, is estimated to be between 60% to 80%.
Choice B is wrong because it exaggerates the risk of schizophrenia for children of affected parents. The risk is about 10%, not 10 times more than the general public.
Choice C is wrong because it gives a false and misleading statistic.
There is no 50% chance that a child will be born with schizophrenia, and there is no evidence that crowded places and high anxiety situations can cause the disorder.
Choice D is wrong because it is based on false and outdated stereotypes. Females with schizophrenia are not infertile and can carry a full-term pregnancy, but most of the people who are affected are male.
