The normal pulse rate for adults is

Correct Answer: B

Rationale: The correct answer is B (60 to 100 beats per minute) as it reflects the typical range for adults. A (25 to 50 bpm) is too low for a healthy adult, C (0 to 50 bpm) includes unrealistic values, and D (50 to 75 bpm) is too narrow as it excludes the higher end of the normal range. A normal adult heart rate falls within the range of 60 to 100 beats per minute, which is important for efficient circulation and oxygen delivery throughout the body.

Correct Answer: D

Rationale: The correct answer is D: Heartburn. GERD commonly presents with heartburn due to the backflow of stomach acid into the esophagus. This symptom is a result of the weakening of the lower esophageal sphincter. Diarrhea (A), lactose intolerance (B), and constipation (C) are not typically associated with GERD. Diarrhea is more commonly linked to infections or certain food intolerances. Lactose intolerance causes symptoms like bloating and gas after consuming dairy, not specifically reflux. Constipation is more related to issues with bowel movements and not typically a symptom 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. People with diabetes may have ketones in their urine due to inadequate insulin levels. Reagents (A) are substances used in chemical reactions, not produced in the body. Glucose (B) is a sugar and is typically found in the blood, not urine in high amounts. Insulin (C) is a hormone that regulates blood sugar levels and is not typically found in urine.

Correct Answer: D

Rationale: The correct answer is D because pressure injuries can lead to life-threatening infections due to compromised skin integrity. When pressure is applied for a prolonged period, blood flow is restricted, leading to tissue damage and making the skin vulnerable to infection. This can result in serious complications if not treated promptly. Choices A, B, and C are incorrect. A pressure injury may not always appear as a deep crater at the initial stage; they can vary in appearance. While pressure injuries can be challenging to heal, they can cause significant pain and discomfort. Finally, although preventing pressure injuries can be difficult, it is not impossible with proper care and interventions.

Correct Answer: D

Rationale: The correct answer is D: Strong smells. Asthma patients should avoid strong smells as they can trigger asthma symptoms. Strong smells like perfumes, smoke, cleaning chemicals can irritate the airways and lead to breathing difficulties. Inhalers (choice A) are actually necessary for asthma management. Talking (choice B) and fluids (choice C) do not directly impact asthma symptoms. In summary, the other choices are incorrect as they do not address the specific trigger for asthma symptoms, which is exposure to strong smells.
