NCLEX RN Predictor Exam
1. What is the BEST blood collection location for a newborn?
- A. the AC
- B. the veins of the forehead
- C. the heel
- D. the fingertips
Correct answer: C
Rationale: When collecting blood from newborns, it is safest and most commonly done by collecting blood from the lateral or medial aspect of the baby's heel. This location is preferred due to the accessibility of the veins and the minimal discomfort caused to the newborn. Veins in the forehead are not commonly used for blood collection in newborns. The fingertips are not optimal for blood collection in newborns due to their small size and the potential for causing discomfort. The AC (antecubital) area, typically used in adults for blood collection, is not recommended for newborns due to the size of their veins and the potential risk of injury.
2. A patient is in the office for a cyst removal and is very anxious about the procedure. Which of the following descriptions of his respirations would be expected?
- A. Bradypnea
- B. Orthopnea
- C. Tachypnea
- D. Dyspnea
Correct answer: C
Rationale: Tachypnea is defined as a rapid, quick, and shallow respiration rate. When a patient is anxious, they may hyperventilate, leading to tachypnea. Bradypnea (Choice A) is slow breathing, which is not expected in an anxious patient. Orthopnea (Choice B) is difficulty breathing while lying down and is not directly related to anxiety. Dyspnea (Choice D) is shortness of breath, which may not be the primary respiratory pattern seen in an anxious patient undergoing a procedure. Therefore, the correct choice is tachypnea as it aligns with the expected respiratory response to anxiety.
3. While performing CPR, a healthcare provider encounters a client with a large amount of thick chest hair when preparing to use an automated external defibrillator (AED). What is the next appropriate action for the healthcare provider?
- A. Apply the pads to the chest and provide a shock
- B. Wipe the client's chest down with a towel before applying the pads
- C. Shave the client's chest to remove the hair
- D. Do not use the AED
Correct answer: C
Rationale: When using an AED, it is crucial for the pads to have good contact with the skin to effectively deliver an electrical shock. While AED pads can adhere to a client's chest even with some hair, thick chest hair can hinder proper current conduction. In such cases, it is recommended to shave the area of the chest where the pads will be applied. Most AED kits include a razor for this purpose. The healthcare provider should act promptly to minimize delays in defibrillation. Option A is incorrect because it may lead to ineffective treatment due to poor pad adherence. Option B is not the best course of action as wiping the chest may not resolve the issue of poor pad contact. Option D is incorrect as not using the AED could jeopardize the client's chance of survival in a cardiac emergency.
4. You have been asked to record the amount of food that the person has eaten during each meal. What kinds of words or numbers would you use to record this food intake?
- A. A little, a moderate amount, or all of the meal
- B. 50 cc, 100 cc, or 500 cc of the meal
- C. 25%, 50%, or 100% of the meal
- D. Either A or C
Correct answer: C
Rationale: Food intake is typically measured in terms of the percentage (%) of food that has been eaten. Using percentages allows for a more precise and standardized way of recording food consumption. For instance, you would record 25% of the vegetable if the person has eaten about a quarter of the vegetables on the plate. Choices A and B are incorrect. Choice A's terms 'a little' and 'a moderate amount' are vague and not specific enough for accurate documentation. Choice B's use of cc is more appropriate for measuring fluids, not solid foods. Choice D is also incorrect as it combines vague terms with percentages, which could lead to confusion in accurately documenting the food intake.
5. Why should a palpated pressure be performed before auscultating blood pressure?
- A. To more clearly hear the Korotkoff sounds.
- B. To detect the presence of an auscultatory gap.
- C. To avoid missing a falsely elevated blood pressure.
- D. To more readily identify phase IV of the Korotkoff sounds.
Correct answer: B
Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.
