What is the MOST ACCURATE statement regarding the ESR test?
- A. The results are diagnostic for certain conditions.
- B. Abnormal results are indicative of a potentially fatal illness.
- C. Abnormal results should be followed by additional testing.
- D. Results are reported in millimeters per hour.
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.

Which of the following activities would the nurse perform during the diagnosing phase of the nursing process? Select all that apply.
- A. Collect and organize client information
- B. Analyze data
- C. Identify problems, risks, and client strengths
- D. Develop nursing diagnoses
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.
After performing the appropriate client assessment, which of the following inferences would the nurse make?
- A. Client is hypotensive
- B. Respiratory rate of 20 breaths per minute
- C. Oxygen saturation of 95%
- D. Client relays anxiety about blood work
Correct Answer: A
Rationale: An inference is the nurse's judgment or interpretation of cues gathered during an assessment. In this scenario, identifying a client as hypotensive would be an inference based on blood pressure readings that indicate lower than normal values. Respiratory rate and oxygen saturation levels (choices B and C) are important cues that provide additional data but do not directly point to a specific conclusion like hypotension. The client expressing anxiety about blood work (choice D) is relevant information but relates more to their emotional state rather than a physiological assessment finding.
To which of the following do the CDC Standard precautions recommendations apply?
- A. Patients with diagnosed infections only
- B. Blood or body fluids with visible blood only
- C. All body fluids including sweat
- D. All patients receiving care in hospitals
Correct Answer: D
Rationale: The correct answer is 'All patients receiving care in hospitals.' Standard precautions apply to all patients in healthcare settings, regardless of their infection status. These recommendations include all body fluids except sweat, non-intact skin, and mucous membranes. Choice A is incorrect as standard precautions are not limited to patients with diagnosed infections. Choice B is incorrect as standard precautions extend beyond blood or body fluids with visible blood. Choice C is incorrect as sweat is an exception to the body fluids covered under standard precautions.
Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?
- A. One light blue, one red
- B. Two lavenders
- C. One lavender, one grey
- D. One green, one red
Correct Answer: D
Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes. Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.
The client reports nausea and constipation. Which of the following would be the priority nursing action?
- A. Collect a stool sample
- B. Complete an abdominal assessment
- C. Administer an anti-nausea medication
- D. Notify the physician
Correct Answer: B
Rationale: The priority nursing action when a client reports symptoms like nausea and constipation is to complete an abdominal assessment. Assessment is crucial as it involves the systematic collection of data to understand the client's condition. By assessing the abdomen, the nurse can gather essential information to make a nursing diagnosis and develop a care plan. Collecting a stool sample (Choice A) may be necessary but comes after the assessment to confirm findings. Administering an anti-nausea medication (Choice C) addresses symptoms but does not address the underlying cause without a thorough assessment. Notifying the physician (Choice D) should come after the assessment to provide a complete picture of the client's condition.
