The nurse caring for an infant demonstrating diarrhea should monitor the infant for which early sign of dehydration?
- A. Cool extremities
- B. Gray, mottled skin
- C. Capillary refill of 3 seconds
- D. Apical pulse rate of 200 beats per minute
Correct Answer: D
Rationale: Dehydration causes interstitial fluid to shift to the vascular compartment in an attempt to maintain fluid volume. When the body is unable to compensate for fluid lost, circulatory failure occurs. The blood pressure will decrease and the pulse rate will increase. This will be followed by peripheral symptoms.

While gathering data, the nurse notes that the client has been prescribed tolterodine tartrate. The nurse should determine that the client is taking the medication to treat which disorder?
- A. Glaucoma
- B. Pyloric stenosis
- C. Renal insufficiency
- D. Urinary frequency and urgency
Correct Answer: D
Rationale: Tolterodine tartrate is an antispasmodic used to treat overactive bladder and symptoms of urinary frequency, urgency, or urge incontinence. It is contraindicated in urinary retention and uncontrolled narrow-angle glaucoma. It is used with caution in renal function impairment, bladder outflow obstruction, and gastrointestinal obstructive disease such as pyloric stenosis.
The nurse evaluates the patency of a peripheral intravenous (IV) site and suspects an infiltration. Which action should the nurse take to determine if the IV has infiltrated?
- A. Strip the tubing and assess for a blood return.
- B. Check the regional tissue for redness and warmth.
- C. Increase the infusion rate and observe for swelling.
- D. Gently palpate regional tissue for edema and coolness.
Correct Answer: D
Rationale: When assessing an IV for clinical indicators of infiltration, it is important to assess the site for edema and coolness, signifying leakage of the IV fluid into the surrounding tissues. Stripping the tubing will not cause a blood return but will force IV fluid into the surrounding tissues, which can increase the risk of tissue damage. Redness and warmth are more likely to indicate infection or phlebitis.
A client is admitted to the hospital with a diagnosis of acute bacterial pericarditis. Which nursing assessment findings are associated with this form of heart disease? Select all that apply.
- A. Fever
- B. Leukopenia
- C. Bradycardia
- D. Pericardial friction rub
- E. Decreased erythrocyte sedimentation rate
- F. Precordial chest pain that intensifies by the supine position
Correct Answer: A,D,F
Rationale: In acute bacterial pericarditis, the membranes surrounding the heart become inflamed and rub against each other, producing the classic pericardial friction rub. Fever typically occurs and is accompanied by leukocytosis and an elevated erythrocyte sedimentation rate. The client complains of severe precordial chest pain that intensifies when lying supine and decreases in a sitting position. The pain also intensifies when the client breathes deeply. Malaise, myalgia, and tachycardia are common.
A pregnant client at 32 weeks' gestation is admitted to the obstetrical unit for observation after a motor vehicle crash. When the client begins experiencing slight vaginal bleeding and mild cramps, which action should the nurse take to support the viability of the fetus?
- A. Insert an intravenous line and begin an infusion at 125 mL per hour.
- B. Administer oxygen to the woman via a face mask at 7 to 10 L per minute.
- C. Position and connect the ultrasound transducer to the external fetal monitor.
- D. Position and connect a spiral electrode to the fetal monitor for internal fetal monitoring.
Correct Answer: C
Rationale: External fetal monitoring will allow the nurse to determine any change in the fetal heart rate and rhythm that would indicate that the fetus is in jeopardy. The amount of bleeding described is insufficient to require intravenous fluid replacement. Because fetal distress has not been determined at this time, oxygen administration is premature. Internal monitoring is contraindicated when there is vaginal bleeding, especially in preterm labor.
The nurse is caring for a client with a diagnosis of pemphigus vulgaris. On assessment of the client, the nurse should look for which sign characteristic of this condition?
- A. Turner's sign
- B. Chvostek's sign
- C. Nikolsky's sign
- D. Trousseau's sign
Correct Answer: C
Rationale: A hallmark sign of pemphigus vulgaris is Nikolsky's sign, which occurs when the epidermis can be rubbed off by slight friction or injury. Other characteristics include flaccid bullae that rupture easily and emit a foul-smelling drainage, leaving crusted, denuded skin. The lesions are common on the face, back, chest, and umbilicus. Even slight pressure on an intact blister may cause spread to adjacent skin. Turner's sign refers to a grayish discoloration of the flanks and is seen in clients with acute pancreatitis. Chvostek's sign, seen in tetany, is a spasm of the facial muscles elicited by tapping the facial nerve in the region of the parotid gland. Trousseau's sign is a sign for tetany, in which carpal spasm can be elicited by compressing the upper arm with a blood pressure cuff inflated above the systolic pressure and causing ischemia to the nerves distally.
