Nursing Elites

1. A patient's urine tests positive for glucose. The doctor asks you to confirm this finding. Which of the following would BEST confirm this finding?

• A. Run the urine on the hand-held glucometer.
• B. Have another MA perform a repeat dipstick test.
• C. Run a Clinitest.
• D. Run an Acetest.

Correct answer: C

Rationale: To confirm glucosuria, the most appropriate method is to run a Clinitest. Clinitest tablets are specifically designed to detect glucose in urine samples. This test is particularly useful when the urine is discolored, making it challenging to accurately assess the color change.\n Choice A, using a hand-held glucometer, is not the standard method for confirming glucose in urine; these devices are primarily used for blood glucose monitoring.\n Choice B, having another Medical Assistant perform a repeat dipstick test, may not provide a more definitive confirmation as dipstick tests can sometimes yield false positives or be less accurate compared to other methods like the Clinitest.\n Choice D, running an Acetest, is used to detect ketones in the urine, not glucose. Ketones are typically associated with conditions like diabetic ketoacidosis, which is different from glucosuria.

2. 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.

3. In the term 'Hemoglobin,' the suffix '-globin' means:

• A. Protein
• B. Iron
• C. Metal
• D. Blood

Correct answer: A

Rationale: The suffix '-globin' in the term 'Hemoglobin' specifically refers to a protein. Hemoglobin is a protein found in red blood cells that carries oxygen. Choice B, 'Iron,' is incorrect as iron is a mineral component of hemoglobin but not the meaning of the suffix. Choice C, 'Metal,' is too broad and not specific to the meaning of the suffix in this context. Choice D, 'Blood,' is incorrect as it refers to the overall term 'Hemoglobin' rather than the specific meaning of the suffix '-globin.' Therefore, the correct answer is A: 'Protein.'

4. Which of these actions illustrates the correct technique for a nurse when assessing oral temperature with a glass thermometer?

• A. Wait 30 minutes if the patient has ingested hot or iced liquids.
• B. Leave the thermometer in place for 3 to 4 minutes if the patient is afebrile.
• C. Shake the glass thermometer down to 35.5°C before taking the patient's temperature.
• D. Place the thermometer at the base of the tongue and ask the patient to close his or her lips.

Correct answer: B

Rationale: The correct technique for assessing oral temperature with a glass thermometer involves leaving the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile. Waiting 30 minutes if the patient has ingested hot or iced liquids is incorrect; instead, the nurse should wait 15 minutes in such cases. Shaking the glass thermometer down to 35.5°C, not 37.5°C, is the correct procedure before taking the patient's temperature. Placing the thermometer at the base of the tongue, not the front, and asking the patient to close their lips is the proper way to position the thermometer. Therefore, the correct answer is to leave the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile.

5. What are Korotkoff sounds?

• A. Sounds noted during diastole.
• B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
• C. Sounds only noted by skilled cardiologists.
• D. Distinct sounds which are classified into 6 phases.

Correct answer: B

Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.
