Nokea
Through which of the following does lymph return to the blood?
- A. Carotid arteries
- B. Inferior vena cava
- C. Aorta
- D. Subclavian veins
Correct Answer: D
Rationale: Lymph returns to the blood circulation through the subclavian veins. The lymphatic system collects excess fluid, proteins, and waste products from the tissues and returns them to the bloodstream. The lymphatic vessels eventually converge into larger lymphatic ducts, and these ducts empty the lymph into the subclavian veins near the heart. From there, the lymph mixes with the blood, allowing it to circulate throughout the body and maintain fluid balance.

Following hypophysectomy, patients require extensive teaching regarding this major alteration in their lifestyle
- A. Abnormal distribution of body hair
- B. Lifetime dependency on hormone replacement
- C. The need to drink many fluids to replace those lost
- D. The need to undergo repeat surgical procedures
Correct Answer: B
Rationale: Following hypophysectomy, which is the surgical removal of the pituitary gland, patients will require lifetime dependency on hormone replacement therapy. The pituitary gland plays a crucial role in regulating various hormones in the body, and without it, the body will not be able to produce essential hormones like growth hormone, thyroid-stimulating hormone, and others. Therefore, hormone replacement therapy is necessary to maintain hormone balance and prevent complications associated with hormone deficiencies. This major alteration in the patient's lifestyle necessitates ongoing medical management and monitoring to ensure hormone levels are maintained within a normal range. The other options (A, C, D) are not directly related to the necessary lifestyle changes following hypophysectomy.
A highly careful mother of a 10-month-old baby boy complains of inadequate weight gain due to refusal of spoon feeding. The LEAST helpful advice is to
- A. respect infant independence
- B. offer softer diet
- C. use 2 spoons (1 for the child and 1 for the parent)
- D. use finger foods
Correct Answer: B
Rationale: Offering softer food may not address the underlying issue of refusal.
A clinic nurse is planning a teaching session about childhood obesity prevention for parents of school-age children. The nurse should include which associated risk of obesity in the teaching plan?
- A. Type I diabetes
- B. Respiratory disease
- C. Celiac disease
- D. Type II diabetes
Correct Answer: D
Rationale: Childhood obesity is strongly associated with an increased risk of developing Type II diabetes. When children are obese, their body's ability to utilize insulin properly can become compromised, leading to insulin resistance and eventually the development of Type II diabetes. This chronic condition can have serious long-term health consequences if not properly managed, making it crucial for parents to understand the link between childhood obesity and Type II diabetes in order to prevent or address it early on.
Which of the following is the medication of choice for anaphylaxis that the nurse should anticipate would be ordered?
- A. Epinephrine
- B. Digoxin (Lanoxin)
- C. Theophylline (Theo-Dur)
- D. Furosemide (Lasix)
Correct Answer: A
Rationale: Epinephrine is the medication of choice for anaphylaxis. Anaphylaxis is a severe and potentially life-threatening allergic reaction that can lead to a rapid drop in blood pressure, airway constriction, and other serious symptoms. Epinephrine acts quickly to reverse these symptoms by constricting blood vessels, relaxing the muscles in the airways, and increasing heart rate. It is administered via an auto-injector device, such as an EpiPen, in cases of severe allergic reactions. Other medications, such as antihistamines and corticosteroids, may be given as adjunct therapy, but epinephrine is the first-line treatment for anaphylaxis. Thus, the nurse should anticipate that epinephrine would be ordered for a patient experiencing anaphylaxis.
Wilma knew that James have an adequate respiratory condition if she notices that
- A. James' respiratory rate is 18
- B. James' Oxygen saturation is 91%
- C. There are frank blood suction from the tube
- D. There are moderate amount of tracheobronchial secretions
Correct Answer: A
Rationale: An adequate respiratory condition can be indicated by a normal respiratory rate. The normal adult respiratory rate typically ranges from 12 to 20 breaths per minute. In this case, if James' respiratory rate is 18, it falls within the normal range and would suggest that his respiratory condition is adequate. Oxygen saturation levels and the presence of blood suction or secretions are important factors to consider as well, but directly assessing the respiratory rate provides a more immediate indication of respiratory status.
