1. Which statement best describes direct contact as a mode of pathogen transmission?
- A. Transmission through large aerosols produced by sneezing or coughing
- B. Transfer of an infectious agent by suspended air particles from a reservoir to a host
- C. Transmission of infectious agents carried by dust
- D. Transmission through skin-to-skin contact or body fluids
Correct answer: D
Rationale: Direct contact transmission occurs when pathogens are spread through skin-to-skin contact or body fluids. This mode of transmission includes activities like touching, kissing, or sexual contact where infectious agents can pass directly from one person to another. It does not involve large aerosols, suspended air particles, or dust as carriers of the pathogen.
2. An elderly female client comes to the clinic for a regular check-up. The client tells the nurse that she has increased her daily doses of acetaminophen (Tylenol) for the past month to control joint pain. Based on this client's comment, what previous lab values should the nurse compare with today's lab report?
- A. Look at last quarter's hemoglobin and hematocrit to assess for dehydration.
- B. Look for an increase in today's LDH compared to the previous one to assess for possible liver damage.
- C. Expect to find an increase in today's APTT compared to last quarter's due to bleeding.
- D. Determine if there is a decrease in serum potassium due to renal compromise.
Correct answer: B
Rationale: When a client increases their daily doses of acetaminophen for joint pain, it raises concerns about possible liver damage due to acetaminophen overdose. LDH (Lactate Dehydrogenase) levels can indicate liver function, so comparing today's levels with previous ones can help assess for liver damage caused by acetaminophen overuse.
3. A nurse is caring for a client who has preeclampsia and is receiving magnesium sulfate. Which action should the nurse take if the client develops toxicity?
- A. Administer calcium gluconate IV
- B. Increase the magnesium sulfate infusion
- C. Administer IV fluids
- D. Administer hydralazine
Correct answer: A
Rationale: In cases of magnesium sulfate toxicity, administering calcium gluconate IV is crucial as it is the antidote for magnesium sulfate. Calcium gluconate helps reverse the effects of magnesium sulfate, especially when signs of toxicity like respiratory depression or loss of reflexes occur. Increasing the magnesium sulfate infusion would worsen toxicity. Administering IV fluids may be beneficial for hydration but does not address magnesium sulfate toxicity. Hydralazine is used to manage hypertension, not magnesium sulfate toxicity.
4. What is the purpose of the pediatric assessment triangle?
- A. Detect immediate life threats through a quick hands-on assessment.
- B. Identify if the child has a medical condition or a traumatic injury.
- C. Determine if the child's problem is respiratory or circulatory in nature.
- D. Form a general impression of the child without touching them.
Correct answer: D
Rationale: The pediatric assessment triangle is used to form a rapid, hands-off general impression of the child's condition without directly touching them. This visual assessment helps in identifying children who require immediate attention and further evaluation.
5. An important characteristic of amino acids is that they can:
- A. act as buffers.
- B. facilitate glucose storage.
- C. regulate heartbeat.
- D. control the level of blood cholesterol.
Correct answer: A
Rationale: The correct answer is A: act as buffers. Amino acids can act as buffers by helping to maintain the pH balance in the body. Choice B is incorrect because amino acids do not primarily facilitate glucose storage. Choice C is incorrect as amino acids do not regulate the heartbeat. Choice D is also incorrect because amino acids do not control the level of blood cholesterol.
