minutes after birth the normal heart rate of the infant may range between:
- A. 100 and 180
- B. 130 and 170
- C. 120 and 160
- D. 100 and 130
Correct Answer: C
Rationale: The normal heart rate of a newborn infant is typically between 120 and 160 beats per minute within the first minutes after birth. This range is considered normal for a healthy newborn and reflects the development of the infant's cardiovascular system. It is important to monitor the newborn's heart rate closely in the immediate post-birth period to ensure that it remains within this normal range. Any deviations from this range may indicate a need for further evaluation and intervention.

During preoperative teaching for a client who will undergo subtotal thyroidectomy, the nurse should include which statement?
- A. "The head of your bed must remain flat for 24 hours after surgery."
- B. "You should avoid deep breathing and coughing after surgery."
- C. "You won't be able to swallow for the first day or two."
- D. "You must avoid hyperextending your neck after surgery."
Correct Answer: D
Rationale: The correct statement to include during preoperative teaching for a client undergoing subtotal thyroidectomy is "You must avoid hyperextending your neck after surgery." This is important because hyperextending the neck can put strain on the suture line and may lead to dehiscence (wound opening). It is crucial for the client to avoid any activities or positions that could compromise the surgical site and hinder proper healing.
A preterm newborn, after spending 8 weeks in the NICU, is being discharged. The parents of the newborn express apprehension and worry that the newborn may still be in danger. How should the nurse interpret these statements?
- A. Normal
- B. A reason to postpone discharge
- C. Suggestive of maladaptation
- D. Suggestive of inadequate bonding
Correct Answer: A
Rationale: It is normal for parents of preterm newborns who have spent time in the NICU to express apprehension and worry upon discharge. The NICU experience can be stressful and overwhelming for families, and it is common for parents to feel anxious about taking their newborn home. The nurse should provide support and education to help alleviate the parents' concerns and ensure a smooth transition from the hospital to home. It is important to acknowledge the parents' feelings, offer reassurance, and reinforce the importance of follow-up care and monitoring.
Which drug class is used to reduce symptoms of muscle weakness from myasthenia gravis?
- A. Anticholinesterase drugs
- B. Adrenergic drugs
- C. Anticholinergic drugs
- D. Beta-blocker drugs
Correct Answer: A
Rationale: Anticholinesterase drugs, such as pyridostigmine, are the primary treatment for myasthenia gravis. These drugs work by preventing the breakdown of acetylcholine, a neurotransmitter that is essential for muscle contractions. By increasing the levels of acetylcholine at the neuromuscular junction, anticholinesterase drugs help improve muscle strength and function in individuals with myasthenia gravis. Adrenergic drugs, anticholinergic drugs, and beta-blocker drugs are not typically used to treat the symptoms of muscle weakness in myasthenia gravis.
