Explanation:
(A) The prone position reduces pressure and tension on the sac. Primary nursing goals are to prevent trauma and infection of the sac. (B) The supine position exerts pressure on the sac. (C) Newborns usually cannot maintain side-lying position. (D) The semi- Fowler position exerts pressure on the sac.

Explanation:
(A) Appropriate endotracheal tube sizes for adults range from 7.0-8.5 mm. (B) Pneumothorax could be indicated by an absence of breath sounds on the affected side. However, in a recently intubated client, the first priority would be to consider tube malposition. (C) During intubation, the right mainstem bronchus can be inadvertently entered if the endotracheal tube is inserted too far. Left mainstem bronchus intubation almost never occurs because of the angle of the left mainstem bronchus. (D) Breath sounds for someone with pneumonia may be decreased over the areas of consolidation. However, in a recently intubated client, the first priority would be to consider tube malposition.

Explanation:
(A) Methylprednisolone sodium succinate is used for its anti-inflammatory effects. (B) Loperamide would be used to control diarrhea. (C) Psyllium may improve consistency of stools by providing bulk. (D) An immunosuppressant such as 6-mercaptopurine is used for chronic unrelenting Crohn's disease.

Explanation
(A) The umbilical area should be kept dry for healing to occur. Moisture is conducive to bacterial growth and therefore could lead to infection at the site. (B) The diaper should be folded below the cord to allow the cord stump to be exposed to the air for healing. (C) The umbilical cord should be swabbed with alcohol at each diaper change to remove urine and stool and to facilitate the desiccation process through drying. (D) Soap and water should not be used to clean the umbilical area because the area could retain moisture, thus making it susceptible to bacterial growth and infection.

(A) Partial thromboplastin time is used to monitor the effects of heparin, and dosage is adjusted depending on test results. It is a screening test used to detect deficiencies in all plasma clotting factors except factors VII and XIII and platelets. (B) Hemoglobin is the main component of RBCs. Its main function is to carry O2from the lungs to the body tissues and to transport CO2back to the lungs. (C) RBC count is the determination of the number of RBCs found in each cubic millimeter of whole blood. (D) PT is used to monitor the effects of oral anticoagulants, e.g., coumarintype anticoagulants.
