Nursing Elites

1. Which of the following measures the frequency of new cases of the phenomenon during a given period of time?

• A. prevalence rate
• B. proportionate mortality rate
• C. case fatality rate
• D. incidence rate

Correct answer: D

Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.

2. Health activities are designed to:

• A. prevent people from being exposed to germs
• B. ignore spiritual factors as they can confuse medical issues
• C. increase communities' control over their health and well-being
• D. ensure that the community health nurse leads health programs

Correct answer: C

Rationale: Health activities are structured to enhance communities' autonomy and influence over their health and well-being, aiming to empower them to make informed choices and take control of their health. Choice A is incorrect as health activities encompass a broader scope beyond just preventing exposure to germs. Choice B is incorrect because spiritual factors are crucial components that should not be disregarded in healthcare. Choice D is incorrect as health activities are not solely about the community health nurse being in charge, but about empowering the community as a whole.

3. A client is admitted with a diagnosis of myocardial infarction (MI). The client is complaining of chest pain. The nurse knows that pain related to an MI is due to

• A. Insufficient oxygenation of the cardiac muscle
• B. Potential circulatory overload
• C. Left ventricular overload
• D. Electrolyte imbalance

Correct answer: A

Rationale: The correct answer is A: Insufficient oxygenation of the cardiac muscle. Myocardial infarction pain is primarily caused by inadequate oxygen reaching the heart muscle, leading to ischemia and tissue damage. Choices B, C, and D are incorrect because circulatory overload, left ventricular overload, and electrolyte imbalance are not the primary causes of chest pain in myocardial infarction. Circulatory overload may lead to other symptoms like edema, left ventricular overload can result in heart failure symptoms, and electrolyte imbalance may present with various manifestations, but none of these directly cause the characteristic chest pain associated with an MI.

4. The community health nurse has been following the care for an adolescent with a history of morbid obesity, asthma, hypertension, and is 22 weeks into a pregnancy. Which of these lab reports sent to the clinic needs to be called to the teen's healthcare provider within the next hour?

• A. Hemoglobin 11 g/dL and calcium 6 mg/dL
• B. Magnesium 0.8 mEq/L and creatinine 3 mg/dL
• C. Blood urea nitrogen 28 mg/dL and glucose 225 mg/dL
• D. Hematocrit 33% and platelets 200,000

Correct answer: B

Rationale: The correct answer is B. The low magnesium level and elevated creatinine suggest possible renal dysfunction, which is concerning, especially in a pregnant client with multiple risk factors such as morbid obesity, asthma, and hypertension. Immediate attention is needed to address the potential renal issues. The other choices do not indicate such urgent conditions. Hemoglobin and calcium levels in choice A are within acceptable ranges. Choice C shows elevated blood urea nitrogen and glucose levels, which may need monitoring but not immediate attention. Choice D's hematocrit and platelet levels are also within normal ranges and do not indicate an urgent issue.

5. The client with acute hypocalcemia is admitted to the unit. Nursing action should include:

• A. Implement seizure precautions
• B. Assess for hypoglycemia
• C. Monitor for visual changes
• D. Observe for muscle weakness

Correct answer: A

Rationale: The correct action for a client with acute hypocalcemia is to implement seizure precautions. Hypocalcemia can lead to tetany and seizures due to neuromuscular irritability. Assessing for hypoglycemia (choice B) is not directly related to hypocalcemia. Monitoring for visual changes (choice C) is more indicative of conditions like hyperglycemia or retinal disorders. Observing for muscle weakness (choice D) is a common symptom of hypocalcemia but does not address the immediate risk of seizures, which is why implementing seizure precautions is the priority nursing action.
