NCLEX RN Predictor Exam
1. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
2. Which desired outcome written by the nurse is correctly written and measurable?
- A. Client will have a normal bowel pattern by April 2
- B. The client will lose 4 lbs. within the next 2 weeks
- C. The nurse will provide skin care at least 3 times each day
- D. The client will breathe better after resting for 10 minutes
Correct answer: B
Rationale: An outcome statement must describe the observable client behavior that should occur in response to the nursing interventions. It consists of a subject, action verb, conditions under which the behavior is to be performed, and the level at which the client will perform the desired behavior. Option B is correctly written and measurable as it includes all the required elements: subject (client), action verb (lose), conditions (within the next 2 weeks), and the level at which the behavior should occur (4 lbs.). Option A lacks the conditions and a specific level, making it not measurable. Option C is a nursing intervention rather than a client goal. Option D does not provide a specific level at which the client should perform the desired behavior, making it not measurable as well.
3. 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.
4. In addition to standard precautions, the nurse caring for a patient with rubella would plan to implement what type of precautions?
- A. Droplet precautions
- B. Airborne precautions
- C. Contact precautions
- D. Universal precautions
Correct answer: A
Rationale: Rubella is an illness transmitted by large-particle droplets, so the nurse should implement droplet precautions in addition to standard precautions. Airborne precautions are used for diseases spread through small particles in the air, such as tuberculosis, varicella, and rubeola. Contact precautions are utilized for diseases transmitted by direct contact with the patient or their environment. Universal precautions and body substance isolations are part of the CDC's standard precautions recommendations, but do not specifically address the transmission route of rubella.
5. To collect timely, specific information, the nurse is most likely to ask which of the following questions?
- A. Would you describe what you are feeling?
- B. How are you today?
- C. What would you like to talk about?
- D. Where does it hurt?
Correct answer: A
Rationale: The correct answer is, 'Would you describe what you are feeling?' This open-ended question prompts the patient to provide subjective data, offering specific information about their current health status and human responses. This information can help identify actual or potential health issues. Choices B and C are more likely to yield general, nonspecific information. Choice D may lead to a brief response or nonverbal indication of pain location. A more effective approach to gather specific information about pain would be to ask, 'Can you describe any pain you are experiencing?'
