Question 1 of 5
For the patient receiving periodic morphine via intravenous push, which of the following findings would be of utmost concern to the nurse?
Correct Answer: C
Rationale: Morphine is an opioid analgesic that can cause respiratory depression as a serious side effect. Decreased respirations are a critical finding because they indicate that the patient may not be receiving adequate oxygenation, which can lead to hypoxia, brain damage, or even death. Increased temperature, decreased bowel sounds, and increased red blood cell count are less concerning in this context. Nurses must monitor respiratory rates closely in patients receiving morphine and be prepared to intervene with naloxone if respiratory depression occurs.
Question 2 of 5
A 13-month-old child recently arrived in the United States from a foreign country with his parents and needs childhood immunizations. His mother reports that he is allergic to eggs. Upon further questioning, you determine that the allergy to eggs is anaphylaxis. Which of the following vaccines should he not receive?
Correct Answer: D
Rationale: The MMR vaccine is cultured in chick embryo fibroblasts and may contain trace amounts of egg protein, posing a risk to individuals with severe egg allergies. Hepatitis B, inactivated polio, and DTaP vaccines do not contain egg proteins and are safe for this child. Precautions should be taken, and the vaccine should be administered under medical supervision if absolutely necessary.
Question 3 of 5
The nurse receives a stat order to administer 50% dextrose solution intravenously to a 1-year-old child with hypoglycemia. How should this drug best be prepared for safe administration to the child?
Correct Answer: C
Rationale: Administering 50% dextrose solution directly to a 1-year-old child is unsafe due to the risk of hyperosmolar injury to veins and tissues. Diluting it 1:1 with sterile water reduces the concentration to 25%, making it safer for pediatric administration. Using a filter needle (A) or tuberculin syringe (B) is not necessary for this preparation. Shaking the solution (D) is inappropriate and could introduce air bubbles.
Question 4 of 5
The process by which a gas is released in a certain substance when added with water
Correct Answer: A
Rationale: The term "effervescent" refers to the process of a gas being released from a substance when added to water. This is commonly observed when certain tablets or powders are added to water, resulting in the production of bubbles or fizz. Mucilage refers to a thick, sticky substance, while spirits typically refer to alcoholic beverages. Collyria are eye drops, and collodion is a solution used in photography and medicine. Therefore, the correct term for the described process is "effervescent."
Question 5 of 5
What is the therapeutic use of levothyroxine?
Correct Answer: C
Rationale: Levothyroxine is a synthetic form of the thyroid hormone thyroxine and is commonly used for the treatment of hypothyroidism. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone to meet the body's needs, leading to various symptoms such as fatigue, weight gain, cold intolerance, and depression. By providing exogenous levothyroxine, the medication helps restore normal thyroid hormone levels in the body, thereby alleviating the symptoms of hypothyroidism and restoring normal hormonal balance. It is important to monitor thyroid hormone levels regularly when on levothyroxine therapy to ensure optimal dosing and maintenance of normal thyroid function.
