NCLEX RN Practice Questions With Rationale
1. A group of nurses who work on the quality assurance council of a unit have gathered to discuss ideas about how to educate their coworkers about Joint Commission requirements. Each of the nurses gives ideas, which are listed together without initial criticism. Eventually, all ideas on the list will be discussed as to their validity. This activity is known as:
- A. Optimizing
- B. Satisficing
- C. Brainstorming
- D. Centralizing
Correct answer: C
Rationale: Brainstorming is the process in which group members generate ideas without immediate criticism or evaluation. This allows for a free flow of creative suggestions. The ideas are then listed together for consideration and discussion of their validity at a later stage. Optimizing, although related to improving efficiency, does not specifically address the initial idea generation process. Satisficing refers to accepting a satisfactory or 'good enough' solution rather than seeking the best possible option, which is not reflective of the scenario described. Centralizing typically refers to consolidating decision-making authority rather than the collaborative idea generation process seen in brainstorming.
2. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?
- A. Contain histamine and provide protection during allergic reactions
- B. Are involved in phagocytosis
- C. Provide protection and immunity against foreign substances
- D. Carry hemoglobin and oxygen to body tissues
Correct answer: C
Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.
3. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?
- A. Ensure that the client does not need surgery
- B. Assess the client's grip strength
- C. Perform an Allen test
- D. Check a serum potassium level
Correct answer: C
Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.
4. A nurse is performing an end-of-shift count of narcotics kept in the locked cabinet. The narcotic log states there should be 26 oxycodone pills left, but there are only 24 in the drawer. What is the first action of the nurse?
- A. Perform the count again
- B. Contact the pharmacy to determine if the narcotic log is incorrect
- C. Check with the last nurse to sign out narcotics from the system
- D. Notify the house supervisor that narcotic medications are missing
Correct answer: A
Rationale: The first action the nurse should take in this situation is to perform the count again. This step is crucial to ensure there was no miscount during the initial check. By verifying the count, the nurse can confirm if there is indeed a discrepancy in the number of oxycodone pills. Contacting the pharmacy, checking with the last nurse, or notifying the house supervisor should only be considered after ensuring the count is accurate. It's important to rule out any human error before escalating the issue to others.
5. Which of the following situations warrants a measurement for orthostatic hypotension?
- A. A 36-year-old male with a spinal injury
- B. An 86-year-old female with significantly altered mental status
- C. A 58-year-old female with near-syncope
- D. A 41-year-old male with acute deep vein thrombosis
Correct answer: C
Rationale: The correct answer is a 58-year-old female with near-syncope. Orthostatic hypotension is a drop in blood pressure of greater than 20 mmHg systolic when moving from a sitting or lying position to standing. Patients at higher risk include those with syncope or near-syncope, symptomatic hypovolemia, and those prone to falls. The other choices are less likely to present with orthostatic hypotension. A spinal injury, altered mental status, and acute deep vein thrombosis are not directly associated with the immediate need for orthostatic hypotension measurement.
