Nokea
The nurse is caring for a patient who has had severe vomiting. The patient's serum sodium level is 130 mEq/L. The nurse will expect the patient's provider to order which treatment?
- A. Diuretic therapy
- B. Intravenous hypertonic 5% saline
- C. Intravenous normal saline 0.9%
- D. Oral sodium supplements
Correct Answer: C
Rationale: In this scenario, the patient has hyponatremia with a serum sodium level of 130 mEq/L. For a serum sodium level between 125 and 135 mEq/L, the appropriate treatment is intravenous normal saline 0.9%. Normal saline helps to increase the sodium content in the vascular fluid. Diuretic therapy would exacerbate sodium and fluid depletion, which is not suitable for a patient already dehydrated from severe vomiting. Intravenous hypertonic 5% saline is typically reserved for severe hyponatremia with a serum sodium level below 120 mEq/L. Oral sodium supplements are not feasible in this case as the patient is vomiting and may not be able to tolerate oral intake easily.

A client has a chest drainage system in place. The fluid in the water seal chamber rises and falls during inspiration and expiration. The nurse interprets this finding as an indication that:
- A. The tube is patent
- B. There is probably a kink in the tubing
- C. Suction should be added to the system
- D. The client is retaining airway secretions
Correct Answer: A
Rationale: The correct answer is A: 'The tube is patent.' When the fluid in the water seal chamber rises and falls during inspiration and expiration, it indicates that the chest tube is patent, allowing for proper drainage. Choice B is incorrect because a kink in the tubing would obstruct the flow of fluid, leading to abnormal fluctuations in the water seal chamber. Choice C is incorrect as adding suction to the system is not indicated based on the described finding. Choice D is incorrect as the rising and falling of fluid in the water seal chamber is not indicative of the client retaining airway secretions.
A nurse is teaching a nursing student how to measure a carotid pulse. The nurse should tell the student to measure the pulse on only one side of the client's neck primarily because:
- A. It is unnecessary to use both hands
- B. Feeling dual pulsations may lead to an incorrect measurement
- C. Palpating both carotid pulses simultaneously could occlude the trachea
- D. Palpating both carotid pulses simultaneously could cause the heart rate and blood pressure to drop
Correct Answer: D
Rationale: The correct answer is D. Applying pressure to both carotid arteries at the same time is contraindicated. Excess pressure to the baroreceptors in the carotid vessels could cause the heart rate and blood pressure to reflexively drop. Palpating both carotid pulses simultaneously could also interfere with the flow of blood to the brain, possibly causing dizziness and syncope. Choices A, B, and C are incorrect. It is necessary to use both hands to measure the carotid pulse accurately. Feeling dual pulsations does not lead to an incorrect measurement, and palpating both carotid pulses simultaneously does not occlude the trachea.
A nurse has a prescription to insert a nasogastric tube into the stomach of an assigned client. Which action should the nurse take to insert the tube safely and easily?
- A. Placing the tube in warm water
- B. Hyperextending the head while inserting the tube
- C. Removing the tube if any resistance to insertion is met
- D. Asking the client to swallow as the tube is being advanced
Correct Answer: D
Rationale: The correct action for the nurse to take to insert a nasogastric tube safely and easily is asking the client to swallow as the tube is being advanced. This action helps facilitate the passage of the tube through the esophagus into the stomach. Placing the tube in warm water (Choice A) is not a recommended practice for nasogastric tube insertion. Hyperextending the head (Choice B) can cause discomfort and is not necessary for safe insertion. Removing the tube if resistance is met (Choice C) is incorrect as it may cause harm or discomfort to the client. Asking the client to swallow helps the tube pass more smoothly and comfortably.
A healthcare professional assesses clients on the medical-surgical unit. Which client is at greatest risk for the development of bacterial cystitis?
- A. A 36-year-old female who has never been pregnant
- B. A 42-year-old male who is prescribed cyclophosphamide
- C. A 58-year-old female who is not taking estrogen replacement
- D. A 77-year-old male with mild congestive heart failure
Correct Answer: C
Rationale: Females are at higher risk of developing bacterial cystitis due to their shorter urethra compared to males. Postmenopausal women not on estrogen replacement therapy are particularly susceptible to cystitis because of changes in vaginal and urethral cells. This increases the risk of bacterial infection. The other options do not have the same level of risk as the postmenopausal woman not using hormone replacement therapy. A never-pregnant middle-aged woman does not have the same increased risk as a postmenopausal woman with hormonal changes.
After delegating care to an unlicensed assistive personnel (UAP) for a client who is prescribed habit training to manage incontinence, a nurse evaluates the UAP's understanding. Which action indicates the UAP needs additional teaching?
- A. Toileting the client after breakfast
- B. Changing the client's incontinence brief when wet
- C. Encouraging the client to drink fluids
- D. Recording the client's incontinence episodes
Correct Answer: B
Rationale: The correct action that indicates the UAP needs additional teaching is choice B, 'Changing the client's incontinence brief when wet.' Habit training is a technique used to manage incontinence, and it is undermined by the use of absorbent incontinence briefs or pads. The nurse should re-educate the UAP on the technique of habit training, which involves scheduled toileting and promoting bladder control. Choices A, C, and D are appropriate actions that support the client's care: toileting the client after meals, encouraging fluid intake, and documenting incontinence episodes are all important aspects of managing incontinence and monitoring the client's condition.
