NCLEX RN Exam Review Answers
1. A patient is being admitted to the ICU with a severe case of encephalitis. Which of these drugs would the nurse not expect to be prescribed for this condition?
- A. Acyclovir (Zovirax)
- B. Mannitol (Osmitrol)
- C. Lactated Ringer's
- D. Phenytoin (Dilantin)
Correct answer: C
Rationale: In the treatment of encephalitis, medications like Acyclovir and Phenytoin are commonly prescribed. Acyclovir is an antiviral medication used to treat viral infections like herpes simplex virus, which can cause encephalitis. Phenytoin is an antiepileptic drug that may be used to manage seizures associated with encephalitis. Mannitol is a diuretic used to reduce intracranial pressure (ICP) by decreasing cerebral edema. Lactated Ringer's solution, on the other hand, is primarily used in fluid replacement therapy and may not be indicated if a patient is at risk for high ICP, as excessive fluid administration could worsen cerebral edema and increase ICP.
2. An infant has just returned to the nursing unit after surgical repair of a cleft lip on the right side. The nurse should place the infant in which best position at this time?
- A. Prone position
- B. On the stomach
- C. Left lateral position
- D. Right lateral position
Correct answer: C
Rationale: After surgical repair of a cleft lip on the right side, the nurse should position the infant carefully to ensure comfort and prevent complications. Placing the infant in the prone position or on the stomach is not recommended as it may cause rubbing of the surgical site against the mattress. The optimal position for the infant is the left lateral position, away from the surgical repair site, to minimize the risk of trauma. Placing the infant on the right lateral position would be contraindicated as it is on the side of the repair. Additionally, positioning the infant upright on the back can help prevent airway obstruction by secretions, blood, or the tongue. Therefore, the correct choice is to place the infant in the left lateral position to promote safety and comfort post cleft lip surgery.
3. While caring for the client during the first hour after delivery, the nurse determines that the uterus is boggy and there is vaginal bleeding. What should be the nurse's first action?
- A. Check vital signs.
- B. Massage the fundus.
- C. Offer a bedpan.
- D. Check for perineal lacerations.
Correct answer: B
Rationale: The nurse's first action should be to massage the fundus until it is firm as uterine atony is the primary cause of bleeding in the first hour after delivery. Massaging the fundus helps to stimulate uterine contractions, which can help control the bleeding. Checking vital signs would be important but addressing the primary cause of bleeding takes precedence. Offering a bedpan is not a priority in this situation as the focus should be on managing the postpartum bleeding. Checking for perineal lacerations is also important but not the initial action needed to address the boggy uterus and vaginal bleeding.
4. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?
- A. The patient is allergic to shellfish.
- B. The patient has a pacemaker.
- C. The patient suffers from claustrophobia.
- D. The patient takes antipsychotic medication.
Correct answer: B
Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.
5. Which of the following glands found in the skin secretes a liquid called Sebum?
- A. Apocrine Glands
- B. Sebaceous Glands
- C. Lacrimal Glands
- D. Sweat Glands
Correct answer: B
Rationale: Sebum is a liquid secreted by glands in the skin known as sebaceous glands. Sebum's primary function is to lubricate the skin and help maintain its integrity. Apocrine glands secrete a different type of sweat that is odorless but can develop an odor when combined with bacteria on the skin. Lacrimal glands produce tears to keep the eyes moist, and sweat glands secrete sweat to regulate body temperature through evaporation. Therefore, the correct answer is Sebaceous Glands because they specifically secrete sebum, distinguishing them from the other gland types mentioned.
