1. A nurse is instructing a patient about the warning signs of Digitalis side effects. Which of the following side effects should the nurse tell the patient are sometimes associated with excessive levels of Digitalis?
- A. Seizures
- B. Muscle weakness
- C. Depression
- D. Anxiety
Correct answer: B
Rationale: The correct answer is 'Muscle weakness.' Palpitations and muscle weakness are commonly associated with excessive levels of Digitalis. Seizures, depression, and anxiety are not typically linked to Digitalis toxicity. Seizures could be more related to other medications or conditions, while depression and anxiety are not commonly reported side effects of Digitalis.
2. A mother of a newborn notices a nurse placing liquid in her baby's eyes. Which of the following is an inaccurate statement about the need for eyedrops following birth?
- A. Eyedrops following birth help reduce the risk of eye infection.
- B. Eyedrops are required by law.
- C. Eyedrops will keep the eye moist.
- D. Eyedrops are required by law every 6 hours following birth.
Correct answer: D
Rationale: The correct answer is 'Eyedrops are required by law every 6 hours following birth.' This statement is inaccurate because while laws do require the placement of eyedrops, physicians indicate a specific timeframe for their administration. Choice A is correct because eyedrops following birth do help reduce the risk of eye infection by preventing ophthalmia neonatorum. Choice B is incorrect as it implies that eyedrops are mandated solely by law, without considering medical reasons. Choice C is accurate as eyedrops do help keep the eye moist, preventing dryness and discomfort.
3. The nurse is caring for a burn victim with a skin graft to the hand. The area is pale and mottled but has good capillary refill. What is the nurse's best action at this time?
- A. Warm the room
- B. Submerge the hand in warm water
- C. Order a K pad and apply to hand
- D. Have the client exercise the fingers to increase blood flow
Correct answer: A
Rationale: The correct action for the nurse to take when caring for a burn victim with a skin graft to the hand, exhibiting pale and mottled skin but good capillary refill, is to warm the room. By warming the room, the nurse helps promote circulation and maintain a conducive environment for healing. Submerging the hand in warm water can pose a risk of injury or infection to the graft site. Ordering a K pad and applying it to the hand may not be necessary at this time and could potentially cause harm. Having the client exercise the fingers to increase blood flow is also not recommended as it may interfere with the healing process of the skin graft.
4. Which type of cells secrete insulin?
- A. alpha cells
- B. beta cells
- C. CD4 cells
- D. helper cells
Correct answer: B
Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.
5. Acyclovir is the drug of choice for:
- A. HIV
- B. HSV 1 and 2 and VZV
- C. CMV
- D. influenza A viruses
Correct answer: C
Rationale: Acyclovir (Zovirax) is specifically used to treat infections caused by herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and varicella-zoster virus (VZV). These include conditions like cold sores, genital herpes, and shingles. Acyclovir works by inhibiting viral DNA replication, leading to the formation of shorter, ineffective DNA chains. It is important to note that acyclovir is not effective against other viruses like HIV, cytomegalovirus (CMV), or influenza A viruses. Therefore, the correct answer is HSV 1 and 2 and VZV.
