Explanation:
(A) A contraindication for ECT is a space-occupying lesion such as a brain tumor. During ECT, intracranial pressure increases. Therefore, ECT would not be prescribed for a client whose intracranial pressure is already elevated. (B) Any cardiac dysrhythmias or complications that arise during ECT are usually attributed to the IV anesthetics used, not to preexisting cardiac structural conditions. (C) Musculoskeletal injuries during ECT are extremely rare because of the IV use of centrally acting muscle relaxers. (D) A history of any kind of infection would not contraindicate the use of ECT. In fact, concurrent treatment of infections with ECT is not uncommon.

Explanation
(A) This measurement is _50 cm (48-49 cm). Fifty centimeters is considered the length necessary for the distal end of the tube to be in place in the stomach. This measurement is too short. (B) This measurement is
_50 cm (47-48 cm). Fifty centimeters is considered the lengthnecessary for the distal end of the tube to be in place in the stomach. This measurement is too short. (C) This measurement gives an approximate indication of the length necessary for the distal end of the tube to be in place in the stomach, but it is not as accurate as actually measuring the client (nose-earxiphoid). (D) This is the correct measurement of 50 cm from the tip of the client's nose to the tip of the earlobe to the xiphoid process (called the NEX [nose-ear-xiphoid] measurement). It is approximately equal to the distance necessary for the distal end of the tube to be located in the correct position in the stomach.

Explanation:
(A) Ovulation is dependent on average length of menstrual cycle, not standard 14 days. (B) Ovulation occurs
14+2 days before next menses (34 minus 14 does not equal 16). (C) Ovulation occurs 14+2 days before next menses (34 minus 14 equals 20). (D) Ovulation occurs 14+2 days before next menses (34 minus 14 does not equal 22).

Explanation
(A) The 6 month old should be examined first. If several children will be examined, begin with the most cooperative and less anxious child to provide modeling. (B) Providing time for play and getting acquainted minimizes stress and anxiety associated with assessment of body parts. (C) Children generally cooperate best when their mother remains with them. (D) Painful areas are best examined last and will permit maximum accuracy of assessment.

Explanation:
(A) Basilar skull fracture may cause dural lacerations, which result in CSF leaking from the ears or nose.
Insertion of a tube could lead to CSF going into the brain tissue or sinuses. (B) Tamponading flow could worsen the problem and increase ICP. (C) Suction could increase brain damage and dislocate tissue. (D) Testing the fluid from the nares would determine the presence of CSF. Elevation of the head, notification of the medical staff, and prophylactic antibiotics are appropriate therapy.
