Which piece of equipment will the nurse routinely use to assess the fetal heart rate of a woman at 16 weeks' gestation?
- A. Fetal heart monitor
- B. An adult stethoscope
- C. Bell of a stethoscope
- D. Ultrasound fetoscope
Correct Answer: D
Rationale: Toward the end of the first trimester, the fetal heart tones can be heard with an ultrasound fetoscope. Options 2 and 3 are not designed to adequately assess the fetal heart rate. A fetal heart monitor is used during labor or in other situations when the fetal heart rate needs continuous monitoring.

A client is admitted to the hospital with a diagnosis of Cushing's syndrome. The nurse monitors the client for which problem that is likely to occur with this diagnosis?
- A. Hypovolemia
- B. Hypoglycemia
- C. Mood disturbances
- D. Deficient fluid volume
Correct Answer: C
Rationale: Cushing's syndrome is a metabolic disorder resulting from the chronic and excessive production of cortisol. When Cushing's syndrome develops, the normal function of the glucocorticoids becomes exaggerated and the classic picture of the syndrome emerges. This exaggerated physiological action can cause mood disturbances, including memory loss, poor concentration and cognition, euphoria, and depression. It can also cause persistent hyperglycemia along with sodium and water retention (hypernatremia), producing edema (hypervolemia; fluid volume excess), and hypertension.
When a client with a chest injury is suspected of experiencing a pleural effusion, which typical manifestations of this respiratory problem should the nurse assess for? Select all that apply.
- A. Dry cough
- B. Moist cough
- C. Dyspnea at rest
- D. Productive cough
- E. Dyspnea on exertion
- F. Nonproductive cough
Correct Answer: A,E,F
Rationale: A pleural effusion is the collection of fluid in the pleural space. Typical assessment findings in the client with a pleural effusion include dyspnea, which usually occurs with exertion, and a dry, nonproductive cough. The cough is caused by bronchial irritation and possible mediastinal shift.
When caring for a client diagnosed with myasthenia gravis, the nurse should be alert for which manifestations of myasthenic crisis? Select all that apply.
- A. Bradycardia
- B. Increased diaphoresis
- C. Decreased lacrimation
- D. Bowel and bladder incontinence
- E. Absent cough and swallow reflex
- F. Sudden marked rise in blood pressure
Correct Answer: B,D,E,F
Rationale: Myasthenic crisis is caused by undermedication or can be precipitated by an infection or sudden withdrawal of anticholinesterase medications. It may also occur spontaneously. Clinical manifestations include increased diaphoresis, bowel and bladder incontinence, absent cough and swallow reflex, sudden marked rise in blood pressure because of hypoxia, increased heart rate, severe respiratory distress and cyanosis, increased secretions, increased lacrimation, restlessness, and dysarthria.
A client states, 'I'm sure I have restless leg syndrome.' The nurse determines that the client is in need of further teaching on the condition when the client identifies the presence of which characteristics? Select all that apply.
- A. A heavy feeling in the legs
- B. Burning sensations in the limbs
- C. Symptom relief when lying down
- D. Decreased ability to move the legs
- E. Symptoms that are worse in the morning
- F. Feeling the need to move the limbs repeatedly
Correct Answer: A,C,D,E
Rationale: Restless leg syndrome is characterized by leg paresthesia associated with an irresistible urge to move. The client complains of intense burning or 'crawling-type' sensations in the limbs and subsequently feels the need to move the limbs repeatedly to relieve the symptoms. The symptoms are worse in the evening and night when the client is still.
A client who has sustained a neck injury is unresponsive and pulseless. What should the emergency department nurse do to open the client's airway?
- A. Insert oropharyngeal airway.
- B. Tilt the head and lift the chin.
- C. Place in the recovery position.
- D. Stabilize the skull and push up the jaw.
Correct Answer: D
Rationale: The health care team uses the jaw-thrust maneuver to open the airway until a radiograph confirms that the client's cervical spine is stable to avoid potential aggravation of a cervical spine injury. Options 1 and 2 require manipulation of the spine to open the airway, and option 3 can be ineffective for opening the airway.
