NCLEX RN Exam Review Answers
1. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?
- A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
- B. It helps your intestines absorb calcium, which is important for bone formation.
- C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
- D. Vitamin D supplements should not be taken by someone of your age.
Correct answer: B
Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.
2. After performing an assessment of an infant with bladder exstrophy, the nurse prepares a plan of care. The nurse identifies which problem as the priority for the infant?
- A. Urinary incontinence
- B. Impaired tissue integrity
- C. Inability to suck and swallow
- D. Lack of knowledge about the disease (parents)
Correct answer: B
Rationale: In bladder exstrophy, the bladder is exposed and external to the body, leading to impaired tissue integrity related to the exposed bladder mucosa as the priority problem. Urinary incontinence is not a concern as the infant is not yet toilet trained. Inability to suck and swallow is unrelated to the disorder. While educating the parents about the condition is important, it is not the priority over addressing the immediate risk of impaired tissue integrity in the infant.
3. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?
- A. Start an IV so contrast media may be given
- B. Ensure that the patient has been NPO for at least 6 hours.
- C. Inform radiology that a radioactive glucose preparation is needed
- D. Instruct the patient to undress to the waist and remove any metal objects
Correct answer: A
Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.
4. When auscultating the patient's lungs during a shift assessment on a patient admitted in the early phase of heart failure, which finding would the nurse most likely hear?
- A. Continuous rumbling, snoring, or rattling sounds mainly on expiration
- B. Continuous high-pitched musical sounds on inspiration and expiration
- C. Discontinuous, high-pitched sounds of short duration heard on inspiration
- D. A series of long-duration, discontinuous, low-pitched sounds during inspiration
Correct answer: C
Rationale: In the early phase of heart failure, fine crackles are likely to be heard upon auscultation of the lungs. Fine crackles are characterized as discontinuous, high-pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration, which are often associated with airway secretions. Coarse crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration, typically indicating fluid in the alveoli. Wheezes are continuous high-pitched musical sounds on inspiration and expiration, commonly heard in conditions like asthma or chronic obstructive pulmonary disease (COPD). Therefore, the correct choice is C, as it describes the expected lung sounds in a patient with early heart failure.
5. You are responsible for reviewing the nursing unit's refrigerator. Which of the following drugs, if found inside the fridge, should be removed?
- A. Nadolol (Corgard)
- B. Opened (in-use) Humulin N injection
- C. Urokinase (Kinlytic)
- D. Epoetin alfa IV (Epogen)
Correct answer: A
Rationale: Nadolol (Corgard) should be removed if found inside the fridge because it is supposed to be stored at room temperature between 59 to 86 ºF (15 and 30 ºC) away from heat, moisture, and light. Storing it in the refrigerator can alter its effectiveness and stability. Option B, the opened Humulin N injection, should not be stored in the refrigerator as it is an in-use product and can remain at room temperature for a certain period as per manufacturer guidelines. Option C, Urokinase (Kinlytic), and Option D, Epoetin alfa IV (Epogen), do not require refrigeration and can be stored at room temperature. Therefore, Nadolol (Corgard) is the drug that should be removed from the fridge.
