Question 1 of 5
When are manual hematocrits done?
Correct Answer: D
Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level.
Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.
Question 2 of 5
Which of the following activities would the nurse perform during the diagnosing phase of the nursing process? Select all that apply.
Correct Answer: B
Rationale: During the diagnosing phase of the nursing process, the nurse analyzes the collected data to identify problems, risks, and client strengths, which then leads to developing nursing diagnoses. Collecting and organizing client information is part of the assessment phase, where data is gathered. Developing nursing diagnoses comes after data analysis in the diagnosing phase. Goal setting is a component of the planning phase, which follows the diagnosing phase.
Question 3 of 5
What is the MOST ACCURATE statement regarding the ESR test?
Correct Answer: C
Rationale: The erythrocyte sedimentation rate (ESR) is a non-specific screening test for inflammation in the body. It is not used as a definitive diagnostic tool for specific conditions. When ESR results are abnormal, they indicate the presence of inflammation, which can be caused by various reasons.
Therefore, abnormal results should be followed by additional testing to determine the underlying cause. The ESR test measures the rate at which red blood cells settle in a vertical tube over the span of one hour, and results are reported in millimeters per hour.
Choice A is incorrect because ESR results are not solely diagnostic for any specific condition.
Choice B is incorrect as abnormal ESR results do not directly indicate a potentially fatal illness without further investigation.
Choice D is incorrect as the results are reported in millimeters per hour, not per minute.
Question 4 of 5
When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?
Correct Answer: C
Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading.
Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue.
Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first.
Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
Question 5 of 5
The functional health pattern assessment data states: 'Eats three meals a day and is of normal weight for height.' The nurse should draw which of the following conclusions about this data? Select all that apply.
Correct Answer: B
Rationale: The assessment data provided indicates a healthy pattern of nutrition and a normal weight for height, suggesting a positive health status. This aligns with a wellness diagnosis, such as 'Potential for enhanced nutrition,' which focuses on improving health further. An actual health problem refers to a current health issue present in the client, which is not evident in this data. Collaborative health problems involve interprofessional collaboration and are not indicated based on the information provided. While a diet assessment may be needed to evaluate food quality, the initial data suggests a wellness-focused approach to care.
