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. A client is about to have a TENS unit attached for pain relief. Which of the following actions is most appropriate in this situation?
- A. Inform the client that he may experience tingling sensations.
- B. Connect the TENS unit before the client goes to bed for the night.
- C. Inform the client that the TENS unit may have pain-reducing effects for 10 to 15 days.
- D. After treatment, inform the client that he may not use a TENS unit again for at least 2 weeks.
Correct answer: A
Rationale: When attaching a TENS unit for pain relief, it is essential to inform the client that he may experience tingling sensations. This is a common sensation experienced when using a TENS unit, but it should not cause muscle twitching. The therapeutic effects of a TENS unit usually last between 3 to 5 days. Choice B is incorrect because there is no specific recommendation to connect the TENS unit before bedtime. Choice C is incorrect as stating that the TENS unit may have pain-reducing effects for 10 to 15 days is inaccurate, as the effects typically last 3 to 5 days. Choice D is incorrect because there is no guideline suggesting that the client cannot use a TENS unit again for at least 2 weeks after treatment.
3. What term is used to refer to generalized wasting of body tissues and malnutrition?
- A. Entropion
- B. Confabulation
- C. Induration
- D. Cachexia
Correct answer: D
Rationale: Cachexia is the correct term used to describe the generalized wasting of body tissues, ill health, and malnutrition associated with some chronic diseases. It involves a loss of fat tissue to protect the bones and joints. Clients with cachexia are at risk of pressure ulcers and other complications due to malnutrition and poor health. Entropion refers to an eyelid condition, confabulation is a memory disturbance, and induration is the abnormal hardening of a part of the body.
4. What does preload refer to?
- A. The volume of blood entering the left side of the heart
- B. The volume of blood entering the right side of the heart
- C. The pressure in the venous system that the heart must overcome to pump the blood
- D. The pressure in the arterial system that the heart must overcome to pump the blood
Correct answer: B
Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.
5. Who is the center of care?
- A. The doctor
- B. The administrator
- C. The patient
- D. The nurse
Correct answer: C
Rationale: The PATIENT is the center of care and the core of the healthcare team. The PATIENT holds the utmost importance within the healthcare setting. Healthcare professionals collaborate as a team to effectively address the needs of the patient. The primary focus should always be on the patient, who plays a crucial role in decision-making. While other healthcare team members, such as doctors, nurses, and administrators, play vital roles, the patient remains the central figure. The patient has the fundamental right to receive quality care from all members of the healthcare team.
