Correct Answer: C

Rationale: Naprosyn (naproxen) is known to cause upper-gastrointestinal (UGI) bleeding due to its effects on the stomach lining. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can irritate the stomach and increase the risk of UGI bleeding. On the other hand, Cardizem (diltiazem), Elavil (amitriptyline), and Corgard (nadolol) are not typically associated with UGI bleeding. Cardizem is a calcium channel blocker used for hypertension and angina, Elavil is a tricyclic antidepressant, and Corgard is a beta-blocker used for hypertension.

Correct Answer: D

Rationale: The correct answer is infant rice cereal. Single-grain infant cereals are recommended as the first solid food because they are easily digestible and have added iron content. Choice C, yogurt, is incorrect because yogurt is a milk product and should be delayed until the child is 12 months old due to the risk of milk allergy. Choices A and B are incorrect because fruits and vegetables are typically introduced after cereals to help the infant get accustomed to solid foods gradually.

Correct Answer: A

Rationale: The correct answer is Good Samaritan laws. These laws protect individuals who provide voluntary emergency care from being held liable for any unintended injury or harm that may occur during the care. Good Samaritan laws encourage individuals to assist in emergencies without fear of legal repercussions. HIPAA, on the other hand, focuses on safeguarding patient information and privacy, ensuring confidentiality. The Patient Self-Determination Act (PSDA) pertains to a patient's rights to make decisions about their medical treatment and advance directives. OBRA, enacted in the late 1980s, aims to improve the quality of care in nursing homes and enhance residents' quality of life, focusing on nursing home reform and standards, which is not directly related to immunity for emergency care providers.

Correct Answer: B

Rationale: The correct answer is that the new graduate irrigates the pressure ulcer with half-strength hydrogen peroxide. Pressure ulcers should not be cleaned with substances that are cytotoxic, such as hydrogen peroxide or betadine. This can cause further damage to the wound and delay the healing process. Choice A is incorrect because irrigating the pressure ulcer with normal saline is an appropriate practice. Choice C is incorrect because packing the wound with sterile kerlix soaked in normal saline is also an appropriate step. Choice D is incorrect because applying a Duoderm dressing after cleansing is a standard procedure in wound care.

Correct Answer: C

Rationale: All nurses should be concerned with preventing the transmission of microorganisms to themselves and others. A primary way to achieve this is through asepsis. Nursing practice emphasizes providing a safe environment to shield clients, family, and healthcare providers from infections. Choices A, B, and D are incorrect. While drug-resistant bacteria, critical microorganisms, and overprescription of bacteriostatic drugs are important, nurses' primary focus should be on preventing microorganism transmission to ensure safety and well-being.
