Explanation:
(A) Placental maturity is assessed by a biophysical profile. (B) L/S ratio and presence of phosphatidylglycerol are not used to determine fetal asphyxia. A biophysical profile score of6 may indicate this condition. (C) Cord compression is not reflected by the L/S ratio or presence of phosphatidylglycerol.
Variable decelerations observed through electronic fetal monitoring could reflect umbilical cord compression. (D) An L/S ratio>2 and the presence of phosphatidylglycerol in amniotic fluid indicate fetal lung maturity.

Section: Questions Set E
Explanation:
(A) A daily dose of fluoxetine should be taken in the morning. Afternoon doses may cause nervousness and insomnia. (B) Although fluoxetine is less sedating than other antidepressants, it may still cause dizziness or drowsiness in some clients. The nurse should caution clients to avoid driving or hazardous activities until the central nervous system effects of the drug are demonstrated. (C) Rashes or pruritus do commonly occur early in therapy and respond to antihistamines or topical corticosteroids. (D) Advise the client not to take over-the- counter or other prescription drugs without consulting with the physician. Fluoxetine does interact with other common drugs such as monoamine oxidase inhibitors, diazepam, insulin, oral antidiabetic agents, tricyclic antidepressants, and tryptophan.

(A)
Of these four goals, maintenance of a calm, quiet atmosphere to reduce anxiety and to allow for rest is the most important. (B) Although nutrition is important, the child needs fluids to maintain fluid and electrolyte balance more than solid foods. In addition, the child may not be able to swallow solid foods owing to epiglottic swelling. (C) This goal is unrealistic because fever is a common symptom of the infection associated with epiglottitis.
(D)
If overexerted, the child will need more O2 and energy than available, and these requirements may exacerbate the condition.

Explanation
(A) A client with a supraglottic (horizontal partial) laryngectomy would require special swallowing training, not a vertical partial laryngectomy. (B) The quality of the client's voice will be altered but adequate for communication. (C) The client will have minimal difficulty swallowing. (D) A radical neck dissection may be done with a total laryngectomy, but not with a partial laryngectomy.

(A) With the slight and mild hard of hearing, auditory training is beneficial. (B) Speech is the most difficult task because it is learned by visual and auditory stimulation, imitation, and reinforcement. (C, D) Lip reading and signing are aimed at establishing communicative skills, but they are learned more easily by visual stimulation.
