The normal pulse rate for adults is

Correct Answer: B

Rationale: The correct answer is B: 60 to 100 beats per minute. This range is considered normal for adults because it reflects a healthy heart rate that can vary based on factors like age, fitness level, and overall health. A pulse rate below 60 may indicate bradycardia, while a rate above 100 may indicate tachycardia. Choices A, C, and D are incorrect because they fall outside the typical normal pulse rate range for adults, which can lead to potential health concerns.

Correct Answer: D

Rationale: The correct answer is D: Heartburn. GERD is characterized by the backflow of stomach acid into the esophagus, leading to a burning sensation in the chest known as heartburn. This symptom is a hallmark of GERD, caused by the weakening of the lower esophageal sphincter. A: Diarrhea is not a common symptom of GERD. B: Lactose intolerance is a separate condition related to the inability to digest lactose, not directly associated with GERD. C: Constipation is also not a typical symptom of GERD, as it primarily involves acid reflux and heartburn. Therefore, the most appropriate choice is D as it aligns with the classic presentation of GERD.

Correct Answer: D

Rationale: The correct answer is D: Ketones. When the body burns fat for energy in the absence of enough insulin, ketones are produced and can be detected in the urine of individuals with diabetes. Ketones are acidic chemicals that can build up in the blood and urine, leading to a condition called diabetic ketoacidosis. Reagents (A) are substances used in chemical reactions, not produced in the body. Glucose (B) is typically found in the urine of individuals with uncontrolled diabetes but is not directly related to fat burning. Insulin (C) is a hormone that helps regulate blood sugar levels and is not a byproduct of fat metabolism.

Correct Answer: D

Rationale: The correct answer is D because pressure injuries can indeed lead to life-threatening infections. When pressure disrupts blood flow to an area, it can result in tissue damage leading to open wounds, which are susceptible to infections. These infections can spread rapidly and become life-threatening if not promptly treated. Choice A is incorrect as skin breakdown in pressure injuries usually starts as redness or discoloration, not a deep crater. Choice B is incorrect as pressure injuries can be painful, especially in later stages. Choice C is incorrect as pressure injuries can be prevented by implementing proper preventive measures such as frequent repositioning and using support surfaces.

Correct Answer: D

Rationale: The correct answer is D: Strong smells. Asthma patients should avoid strong smells as they can trigger asthma symptoms. Strong odors from perfumes, cleaning products, and smoke can irritate the airways and lead to asthma attacks. Avoiding strong smells can help in managing asthma symptoms and preventing exacerbations. Incorrect answers: A: Inhalers - Inhalers are essential for managing asthma symptoms and should not be avoided. B: Talking - Talking does not directly affect asthma symptoms. C: Fluids - Staying hydrated is important for overall health and does not specifically impact asthma management.
