Nursing Elites

1. When are manual hematocrits done?

• A. to monitor anemia
• B. by using a microhematocrit tube.
• C. to measure the percentage of plasma to cells.
• D. All of the above.

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.

2. The NFPA diamond has four colors. The blue diamond:

• A. indicates hazards to health.
• B. designates that it is safe to use water to put out this type of fire.
• C. indicates that ice is necessary to treat an injury with this type of chemical.
• D. indicates that the chemical may be incinerated upon disposal.

Correct answer: A

Rationale: The National Fire Protection Agency (NFPA) uses a safety diamond to communicate the level of threat posed by a specific chemical. The blue diamond in the NFPA diamond system signifies potential health hazards associated with the use of that chemical. Choice B is incorrect because the blue diamond does not indicate anything about using water to extinguish fires. Choice C is incorrect as the NFPA diamond does not provide information on treating injuries. Choice D is also incorrect as the blue diamond does not suggest incineration upon disposal; it pertains to health hazards.

3. During an assessment, a nurse asks a patient, "If you had fever and vomiting for 3 days, what would you do?"? Which aspect of the mental status examination is the nurse assessing?

• A. Behavior
• B. Cognition
• C. Affect and mood
• D. Perceptual disturbances

Correct answer: B

Rationale: The nurse is assessing cognition in this scenario. Cognition involves evaluating a patient's judgment and decision-making abilities. By asking the patient what they would do in a specific situation, the nurse aims to determine the patient's cognitive function. A correct response indicating intact cognition would involve a decision like 'Call my doctor.' If the patient suggests inappropriate actions like 'I would stop eating' or 'I would just wait and see what happened,' it would suggest impaired judgment. The other options, behavior, affect and mood, and perceptual disturbances, refer to different aspects of the mental status examination and are not directly assessed through this question.

4. Why should direct care providers avoid glued-on artificial nails?

• A. Interfere with dexterity of the fingers.
• B. Could fall off in a patient's bed.
• C. Harbor microorganisms.
• D. Can scratch a patient.

Correct answer: C

Rationale: Direct care providers, including nurses, should avoid glued-on artificial nails because studies have shown that artificial nails, especially when cracked, broken, or split, create crevices where microorganisms can thrive and multiply. This can lead to an increased risk of transmitting infections to patients. Therefore, the primary reason for avoiding glued-on artificial nails is their potential to harbor harmful microorganisms, making option C the correct choice. Options A, B, and D are incorrect because while they may present some issues, the primary concern is the risk of microbial contamination associated with artificial nails.

5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?

• A. Yield a falsely low blood pressure
• B. Yield a falsely high blood pressure
• C. Be the same, regardless of cuff size
• D. Vary as a result of the technique of the person performing the assessment

Correct answer: B

Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
