1. Elderly patients are more prone to dehydration than younger people because the elderly ___________.

• A. drink more coffee and tea
• B. have more stomach mucus production
• C. have more saliva
• D. have less sense of thirst

Correct answer: D

Rationale: Elderly patients are prone to dehydration because they have a lower and diminished sense of thirst. This reduced sensation of thirst makes them less likely to drink an adequate amount of fluids, leading to dehydration. While it is true that elderly individuals may also have changes such as decreased stomach mucus production and saliva production, these factors do not directly contribute to dehydration. Drinking more coffee and tea, as mentioned in choice A, is not a consistent behavior among all elderly individuals and is not a primary reason for their increased risk of dehydration.

2. The key to the prevention of a pandemic influenza is:

• A. Early detection
• B. Early antibiotic treatment
• C. Vaccination of at-risk populations
• D. Isolation of suspected cases

Correct answer: A

Rationale: The key to preventing a pandemic influenza is early detection. Detecting influenza cases early allows for timely public health responses to limit the spread of the virus. Early detection helps in implementing measures such as isolation, treatment, and vaccination to prevent the development of a full-blown pandemic. Antibiotics are not effective against influenza viruses, so early antibiotic treatment is not the key to prevention. While vaccination of at-risk populations is important in controlling the spread of influenza, early detection is crucial as it allows for timely implementation of vaccination strategies. Isolation of suspected cases is a containment measure rather than a prevention strategy; the key to prevention lies in early detection to stop the spread before it becomes a pandemic.

3. A complication of osteoporosis is _______________?

• A. rheumatoid arthritis
• B. gouty arthritis
• C. dorsiflexion
• D. joint deformity

Correct answer: D

Rationale: Joint deformity is a well-known complication of osteoporosis, leading to structural changes in the joints due to bone loss and fragility. Gouty arthritis and rheumatoid arthritis are distinct types of arthritis that are not direct complications of osteoporosis. Dorsiflexion is a movement related to the foot's range of motion and is not a typical complication of osteoporosis.

4. Mrs. F has been diagnosed with hyperparathyroidism. Which of the following complications is Mrs. F at highest risk of developing?

• A. Hyponatremia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypercalcemia

Correct answer: D

Rationale: The parathyroid glands regulate calcium, vitamin D, and phosphorus in the body. Hyperparathyroidism leads to excessive production of parathyroid hormone, causing the release of calcium from bones into the bloodstream, resulting in elevated blood calcium levels, known as hypercalcemia. This puts individuals at risk of developing complications such as kidney stones, bone pain, osteoporosis, and neuropsychiatric symptoms. The other options, hyponatremia, hypocalcemia, and hypermagnesemia, are not directly associated with hyperparathyroidism. Hyponatremia is low sodium levels in the blood, hypocalcemia is low calcium levels, and hypermagnesemia is high magnesium levels, which are not typically seen in hyperparathyroidism.

5. Which of the following conditions may cause an increased respiratory rate?

• A. Stooped posture
• B. Narcotic analgesics
• C. Injury to the brain stem
• D. Anemia

Correct answer: D

Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen. Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.
