Dr. Smith orders a gram of human salt poor albumin product for a patient. The product is available in a 50-milliliter vial with a concentration of 25 percent. What dosage will the nurse administer?

Correct Answer: A

Rationale: To calculate the dosage of human salt poor albumin product that the nurse will administer, we need to determine the volume of product containing 1 gram of albumin.

Correct Answer: C

Rationale: NREM stage 3, deep sleep, restores energy-lack causes fatigue and mood dips, per sleep physiology. Stage 1 is lightest, anxiety-sensitive. Dreaming is REM, not here-irritability ties to REM loss. Paradoxical is REM. Deep sleep's role explains EEG focus, answering accurately.

Correct Answer: D

Rationale: Prescription-only medicines are included in Schedule IV of the Controlled Substances Act. Schedule IV controlled substances have a lower potential for abuse compared to drugs in Schedules I, II, and III. These prescription medications still require a prescription from a healthcare provider, but they have a lower potential for abuse and addiction, which allows them to be categorized in Schedule IV. Examples of Schedule IV substances include certain tranquilizers and sedatives like Xanax and Valium.

Correct Answer: A

Rationale: Colloids, such as albumin and synthetic colloids like hydroxyethyl starch, do not enhance the oxygen-carrying capacity of the blood. They can help to increase the intravascular volume in cases of hypovolemia by osmotically drawing fluid into the intravascular space. This can help improve tissue perfusion by increasing blood pressure. Colloids do not have a direct effect on oxygen-carrying capacity or coagulation properties. Dextran therapy can cause adverse effects like anaphylaxis or renal failure, but it is not a general contraindication for all colloid administration in the treatment of hypovolemia.

Correct Answer: B

Rationale: Carbamazepine carries teratogenic risks (e.g., neural tube defects), making it unsafe in pregnancy. Digoxin is safe, used for fetal arrhythmias or maternal heart conditions, with no major congenital risks, a true statement. Streptomycin causes ototoxicity in the fetus, and methotrexate, a folate antagonist, is highly teratogenic, both unsafe. Propylthiouracil is also safe but not listed here correctly per the key. Digoxin's safety profile in pregnancy makes it a preferred option for cardiac issues, balancing maternal and fetal needs.
