1. A nurse is preparing to insert a small-bore nasogastric feeding tube for a client's enteral feedings. In which method does the nurse measure the correct length of the tube?
- A. From the tip of the nose to the xiphoid process
- B. From the tip of the nose to the earlobe to the xiphoid process
- C. From the earlobe to the xiphoid process
- D. From the tip of the nose to the earlobe to the umbilicus
Correct answer: B
Rationale: When preparing to insert a nasogastric tube, the nurse must measure the correct length to ensure that the end of the tube will be in the correct position in the stomach. The accurate method to measure the length is from the tip of the nose to the earlobe to the xiphoid process. This length ensures that the end of the tube reaches the stomach, avoiding placement in the small intestine or esophagus. Choice A is incorrect as it does not include the earlobe, which is essential for accurate measurement. Choice C is incorrect because measuring from the earlobe alone does not provide the correct length for positioning in the stomach. Choice D is incorrect as it includes the umbilicus, which is not the appropriate landmark for measuring the length of a nasogastric tube intended for stomach placement.
2. The nurse is preparing to examine a 6-year-old child. Which action is most appropriate?
- A. The child is asked to undress from the waist up.
- B. The head is examined before the thorax, abdomen, and genitalia.
- C. The nurse should keep in mind that a child at this age will have a sense of modesty.
- D. Talking about the equipment being used is avoided to prevent increasing the child's anxiety.
Correct answer: C
Rationale: When examining a 6-year-old child, it is important to consider their sense of modesty. The child should undress themselves, leaving underpants on and using a gown or drape to maintain privacy. Additionally, a school-age child like a 6-year-old is curious about how equipment works, so it is beneficial to explain the purpose and function of the tools being used. The examination sequence should typically progress from the child's head to the toes to ensure a thorough assessment. Therefore, choices A, B, and D are incorrect as they do not align with the appropriate approach to examining a 6-year-old child.
3. Which of the following safety precautions should the nurse discuss when working with an immunocompromised client?
- A. Avoid canned foods and increase consumption of fresh fruits and vegetables
- B. Hand-wash utensils after use and allow them to air dry
- C. Only drink tap water that has been filtered or boiled before consumption
- D. Never eat meals prepared in restaurants
Correct answer: C
Rationale: The correct answer is to only drink tap water that has been filtered or boiled before consumption. Immunocompromised clients are susceptible to infections, so it is essential to take precautions to prevent exposure to harmful pathogens. Drinking tap water that has been filtered or boiled helps eliminate potential pathogens that could be harmful to the client's health. Choices A, B, and D do not directly address the issue of avoiding potential pathogens that could compromise the health of an immunocompromised client. Thus, they are incorrect. Hand-washing utensils, avoiding canned foods, and increasing fruit and vegetable consumption are good general hygiene practices but may not specifically address the needs of an immunocompromised client.
4. Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?
- A. PT/INR
- B. CBC
- C. PTT
- D. WBC
Correct answer: A
Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin. Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy. Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy. Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.
5. Patients exhibiting signs of cyanosis will:
- A. show signs of hyperoxia.
- B. have increased O2 saturation.
- C. have blood levels of CO2 higher than O2 levels.
- D. None of the above.
Correct answer: C
Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.
