Sometimes, people with congestive heart failure develop arrhythmias of the heart. These irregular rhythms can be conducive to developing a blood clot. Physicians frequently treat people with 'blood thinning' medicines that require regulation of the density of the blood. Which of these is the name for a blood-thinner?
- A. Erythromycin
- B. Tetracycline
- C. Warfarin
- D. Amoxicillin
Correct Answer: C
Rationale: Warfarin is a medication commonly used as a blood thinner to prevent blood clot formation. It works by inhibiting the clotting factors in the blood, thereby reducing the risk of clot formation and helping in the management of conditions like congestive heart failure and arrhythmias. Choices A, B, and D are antibiotics and do not have blood-thinning properties like Warfarin.

A mother reported to you that her 6-year-old child is suffering from diarrhea. Which of the following advice will you give to the mother?
- A. Breastfeeding should be continued day and night
- B. Formula milk should be stopped for 6 hours
- C. Breast milk can be given together with oral rehydration salts
- D. A and C
Correct Answer: D
Rationale: When a child is suffering from diarrhea, it is essential to continue breastfeeding day and night to maintain hydration and provide necessary nutrients. Stopping formula milk for 6 hours (choice B) is not the recommended approach as it may lead to a lack of essential nutrients during this critical time. Giving breast milk together with oral rehydration salts (choice C) can help replenish lost fluids and electrolytes, making it a suitable recommendation. Therefore, advising the mother to follow both options A and C is the most appropriate approach to manage the child's condition effectively.
To prevent diarrhea in children, a vaccine is available against which of the following?
- A. Adenovirus
- B. Rotavirus
- C. Enterovirus
- D. All of the above
Correct Answer: B
Rationale: The correct answer is B - Rotavirus. Rotavirus vaccine is available to prevent diarrhea in children. Rotavirus is a common cause of severe diarrhea in infants and young children globally, and vaccination has been shown to be effective in reducing the burden of this disease. Choices A and C are incorrect because there is no specific vaccine available for Adenovirus or Enterovirus to prevent diarrhea in children. Choice D is incorrect because while vaccines are available for some viruses that can cause diarrhea in children, not all mentioned in the choices have a specific vaccine available.
Which of the following is not an infectious cause of diarrhea?
- A. Allergy
- B. Bacteria
- C. Parasite
- D. Virus
Correct Answer: A
Rationale: The correct answer is A: Allergy. Allergy is not an infectious cause of diarrhea. Diarrhea caused by bacteria, parasites, and viruses is due to infection, while an allergy triggers an immune response that can lead to diarrhea but is not caused by an infectious agent. Choices B, C, and D are incorrect because bacteria, parasites, and viruses are known infectious causes of diarrhea, resulting from infections by these microorganisms.
A new mother asks the nurse when she should begin to breastfeed her newborn. The nurse's best response is:
- A. Within the first half-hour after birth
- B. After the newborn's first bath
- C. When the newborn begins to cry
- D. After administering vitamin K
Correct Answer: A
Rationale: Initiating breastfeeding within the first half-hour after birth is crucial for successful breastfeeding and bonding, as recommended by the World Health Organization. This early initiation helps establish breastfeeding and supports the newborn's health by providing colostrum, the nutrient-rich first milk. Choice B, 'After the newborn's first bath,' is incorrect because initiating breastfeeding should not be delayed after birth. Choice C, 'When the newborn begins to cry,' is incorrect as it does not promote timely initiation of breastfeeding. Choice D, 'After administering vitamin K,' is incorrect because breastfeeding initiation should not be delayed for this procedure.
The client is being taught about perineal care postpartum. Which instruction should the client receive?
- A. Use ice packs to reduce swelling for the first 24 hours.
- B. Apply heat packs immediately after birth to reduce pain.
- C. Avoid using a peri-bottle to cleanse the perineum.
- D. Use tampons to absorb lochia discharge.
Correct Answer: A
Rationale: The correct instruction for the client postpartum is to use ice packs to reduce swelling for the first 24 hours. This helps alleviate discomfort and promote healing. Applying heat packs immediately after birth is not recommended as they can increase swelling. A peri-bottle is advised for cleansing the perineum, not to be avoided. Tampons should not be used to absorb lochia discharge as they can increase the risk of infection. Therefore, the use of ice packs is the most appropriate and beneficial instruction for perineal care postpartum.
