A client is in early labor. Her fetus is in a left occipitoanterior (LOA) position; fetal heart sounds are best auscultated just:
- A. Below the umbilicus toward left side of mother's abdomen
- B. Below the umbilicus toward right side of mother's abdomen
- C. At the umbilicus
- D. Above the umbilicus to the left side of mother's abdomen
Correct Answer: A
Rationale: In LOA, the fetus's back is on the mother's left anterior side, so fetal heart sounds are best heard below the umbilicus on the left.

Forty-eight hours after a thyroidectomy, a female client complains of numbness and tingling of the toes and fingers. The nurse notes upper arm and facial twitching. The nurse needs to:
- A. Report the findings to the physician
- B. Assist the client to do range of motion exercises
- C. Check the client's potassium level
- D. Administer the as-needed dose of phenytoin (Dilantin)
Correct Answer: A
Rationale: Muscular hyperactivity and parasthesias may indicate hypocalcemic tetany and require immediate administration of calcium gluconate. Tetany can occur if the parathyroid glands were erroneously excised during surgery. Range of motion exercises are not appropriate to presenting symptoms. These characteristics are not usual signs of potassium imbalance, but of calcium imbalance. Phenytoin is indicated for seizure activity mainly of neurological origin.
The client is prescribed digoxin (Lanoxin) for heart failure. Which instruction should the nurse include in the teaching plan?
- A. Take the medication with meals to prevent nausea.'
- B. Report a pulse below 60 beats per minute.'
- C. Increase potassium-rich foods in your diet.'
- D. Take an extra dose if you miss one.'
Correct Answer: B
Rationale: Digoxin toxicity is increased with bradycardia, so a pulse below 60 beats per minute should be reported. It can be taken with or without food, potassium monitoring is important but not increasing, and extra doses are dangerous.
A client arrives in the emergency room with severe burns of the hands, right arm, face, and neck. The nurse needs to start an IV.
- A. Top of client's right hand
- B. Left antecubital fossa
- C. Top of either foot
- D. Left forearm
Correct Answer: B
Rationale: The left antecubital fossa is suitable for IV placement, avoiding burned areas (right hand, arm, face, neck). The foot (C) is less ideal due to infection risk, and the left forearm (D) may be too close to burn sites.
Prior to his discharge from the hospital, a cardiac client is started on digoxin (Lanoxin) 25 mg po qd. The nurse initiates discharge teaching. Which of the following statements by the client would validate an understanding of his medication?
- A. I would notify my physician immediately if I experience nausea, vomiting, and double vision.'
- B. I could stop taking this medication when I begin to feel better.'
- C. I should only take the medication if my heart rate is greater than 100 bpm.'
- D. I should always take this medication with an antacid.'
Correct Answer: A
Rationale: The first signs of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, and visual disturbances. The physician should be notified if any of these symptoms are experienced. The positive inotropic effects of digoxin increase cardiac output and result in an enhanced activity tolerance. 'Feeling better' indicates the drug is working and medication therapy must be continued. Clients should be taught to take their pulse prior to taking the digoxin. If their pulse rate becomes irregular, slows significantly, or is >100 bpm the physician should be notified. Antacids decrease the effectiveness of digoxin.
The client is diagnosed with glaucoma. Which medication is most likely to be prescribed?
- A. Timolol (Timoptic)
- B. Atropine (Isopto Atropine)
- C. Pilocarpine (Isopto Carpine)
- D. Acetazolamide (Diamox)
Correct Answer: A
Rationale: Timolol, a beta-blocker, is commonly prescribed for glaucoma to reduce intraocular pressure by decreasing aqueous humor production. Atropine increases pressure, pilocarpine is less common, and acetazolamide is used acutely.
