NCLEX RN Practice Questions Exam Cram
1. A woman in her third trimester complains of severe heartburn. What is appropriate teaching by the nurse to help the woman alleviate these symptoms?
- A. Drink small amounts of liquids frequently
- B. Eat the evening meal at least 2-3 hours before bedtime
- C. Take sodium bicarbonate after each meal
- D. Sleep with head propped on several pillows
Correct answer: D
Rationale: During the third trimester, many women experience heartburn due to the pressure of the growing uterus on the stomach. Elevating the head while sleeping can help prevent gastric contents from refluxing back into the esophagus, thus reducing heartburn symptoms. Drinking small amounts of liquids frequently may exacerbate heartburn by increasing stomach distension. Eating the evening meal just before retiring can also worsen heartburn symptoms as lying down shortly after eating can promote reflux. Taking sodium bicarbonate after each meal is not recommended as it can disrupt the body's natural pH balance and lead to other complications.
2. Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?
- A. Increasing heart rate above normal for the patient's age.
- B. Absent peripheral pulses
- C. Decreasing level of consciousness
- D. Increasing blood pressure
Correct answer: D
Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.
3. Your patient has shown the following signs and symptoms: Feeling very thirsty, large amount of water intake, dryness of the mouth, and urinary frequency. What physical disorder does this patient most likely have?
- A. Diabetes
- B. Angina
- C. Hypertension
- D. Hypotension
Correct answer: A
Rationale: The patient is exhibiting classic signs of diabetes, such as polydipsia (feeling very thirsty), polyuria (large amount of water intake and urinary frequency), and xerostomia (dryness of the mouth). These symptoms are indicative of high blood glucose levels, which are characteristic of diabetes. Other common signs of diabetes include poor vision, unexplained weight loss, peripheral neuropathy (tingling in the feet and hands), and fatigue. Angina is chest pain due to reduced blood flow to the heart, not associated with the symptoms described in the patient. Hypertension is high blood pressure, which typically does not present with these specific symptoms related to diabetes. Hypotension is low blood pressure and is not consistent with the signs and symptoms presented by the patient, pointing more towards diabetes as the likely diagnosis.
4. A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?
- A. It is an acute bowel obstruction.
- B. It is a condition that causes an acute inflammatory process in the bowel.
- C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
- D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.
Correct answer: D
Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.
5. 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.
