NCLEX RN Exam Preview Answers
1. While auscultating heart sounds, the nurse hears a murmur. Which of these instruments would be used to assess this murmur?
- A. Electrocardiogram
- B. Bell of the stethoscope
- C. Diaphragm of the stethoscope
- D. Palpation with the nurse's palm of the hand
Correct answer: B
Rationale: The correct instrument to assess a murmur while auscultating heart sounds is the bell of the stethoscope. An electrocardiogram is used to measure the heart's electrical activity, not to assess murmurs. Palpation with the nurse's palm of the hand is a method to assess pulses or textures, not heart murmurs. The diaphragm of the stethoscope is typically used for high-pitched sounds like breath, bowel, and normal heart sounds, whereas the bell is more suitable for soft, low-pitched sounds such as murmurs or extra heart sounds.
2. When caring for a single client during one shift, it is appropriate for the nurse to reuse only which of the following personal protective equipment?
- A. Goggles
- B. Gown
- C. Surgical mask
- D. Clean gloves
Correct answer: A
Rationale: Goggles may be reused unless they are overly contaminated by material that has splashed in the nurse's face and cannot be effectively rinsed off. Gowns are at high risk for contamination and should be used only once and then discarded or washed. Surgical masks and gloves should never be washed or reused. Goggles provide eye protection from splashes and should be cleaned and disinfected after each use to ensure proper protection.
3. A client is preparing to irrigate a colostomy. Which of the following situations is a contraindication for this type of irrigation?
- A. The client has an incontinent ostomy
- B. The client has an irregular bowel routine
- C. The client has diverticulitis
- D. The colostomy bag contains fecal material
Correct answer: C
Rationale: When a client with a colostomy is preparing for irrigation, it is essential to consider contraindications that could pose risks or worsen the client's condition. Diverticulitis is a contraindication for colostomy irrigation because the inflamed diverticula could be further irritated by the flushing action during irrigation, potentially leading to complications. An incontinent ostomy, irregular bowel routine, or presence of fecal material in the colostomy bag are not specific contraindications for irrigation and can be managed through appropriate techniques and interventions.
4. What procedure examines a portion of the large intestine with an endoscope?
- A. Colposcopy
- B. Sigmoidoscopy
- C. Upper GI
- D. Cardiac catheterization
Correct answer: B
Rationale: Sigmoidoscopy is the correct answer because it specifically examines the sigmoid colon located in the descending colon using an endoscope inserted through the rectum. This procedure captures video and images of the large intestine's lining, helping in the diagnosis of conditions like inflammatory bowel disease or colorectal cancer. Colposcopy, on the other hand, is a procedure for examining the cervix and vagina, not the large intestine. Upper GI involves capturing images of the esophagus and stomach, focusing on the upper gastrointestinal tract, not the large intestine. Cardiac catheterization is a procedure that involves threading a thin instrument through the femoral artery to the heart, used for cardiac interventions and not related to examining the large intestine.
5. During the general survey, what action is a component of the assessment?
- A. Observing the patient's body stature and nutritional status
- B. Interpreting the subjective information reported by the patient
- C. Measuring the patient's temperature, pulse, respirations, and blood pressure
- D. Observing specific body systems during the physical assessment
Correct answer: A
Rationale: During the general survey, the nurse assesses the patient's overall appearance, body structure, mobility, and behavior, which includes observing body stature and nutritional status. Interpreting subjective information reported by the patient is part of the subjective data collection process and not the general survey. Measuring vital signs like temperature, pulse, respirations, and blood pressure is part of a focused physical examination, not the general survey. Additionally, observing specific body systems while performing a physical assessment is more specific and focused than the general survey.
