1. A new mother has some questions about phenylketonuria (PKU). Which of the following statements made by a nurse is not correct regarding PKU?
- A. A Guthrie test can check the necessary lab values.
- B. The urine has a high concentration of phenylpyruvic acid
- C. Mental deficits are often present with PKU
- D. The effects of PKU are reversible
Correct answer: D
Rationale: Phenylketonuria (PKU) is an inherited disorder that increases the levels of phenylalanine (a building block of proteins) in the blood. If PKU is not treated, phenylalanine can build up to harmful levels in the body, causing intellectual disability and other serious health problems. The signs and symptoms of PKU vary from mild to severe. The most severe form of this disorder is known as classic PKU. Infants with classic PKU appear normal until they are a few months old. Without treatment, these children develop a permanent intellectual disability. Seizures, delayed development, behavioral problems, and psychiatric disorders are also common. Untreated individuals may have a musty or mouse-like odor as a side effect of excess phenylalanine in the body. Children with classic PKU tend to have lighter skin and hair than unaffected family members and are also likely to have skin disorders such as eczema. The effects of PKU stay with the infant throughout their life (via Genetic Home Reference).
2. You are taking care of Mary Eden, an elderly and frail 91-year-old resident. She gets confused during evening hours and at times she thinks that she hears her daughter calling her from the other side of the nursing home. Which physical problem places Mary Eden at risk for falls?
- A. Her confusion
- B. Her daughter
- C. Evening hours
- D. Her frailness
Correct answer: D
Rationale: Mary Eden's frail and weak muscles due to her age and physical condition place her at risk for falls. While her confusion can contribute to falls, it is considered an emotional or cognitive issue rather than a physical problem. Her daughter and the evening hours are not physical problems that directly increase her risk of falling.
3. Which of the following conditions may warrant a serum creatinine level?
- A. Rhabdomyolysis
- B. Digitalis toxicity
- C. Glomerulonephritis
- D. All answers are correct
Correct answer: D
Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.
4. Mary T. was admitted to a nursing home on May 1st. On July 4th, she was diagnosed with a skin infection. This infection is considered a ________________ infection.
- A. nosocomial
- B. systemic
- C. resident flora
- D. resident aura
Correct answer: A
Rationale: The correct answer is 'nosocomial.' A nosocomial infection is defined as one that is not present upon admission to a healthcare facility but instead occurs during the patient's stay. In this case, since Mary was diagnosed with a skin infection after being admitted to the nursing home, it is considered a nosocomial infection. Nosocomial infections are a significant concern in healthcare settings, and infection control measures are in place to prevent their spread. Choices B, C, and D are incorrect. 'Systemic' refers to a condition affecting the entire body, not specific to a healthcare setting. 'Resident flora' and 'resident aura' are not commonly used terms in healthcare and do not relate to infections acquired in healthcare facilities.
5. Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?
- A. The test determines if the client is anemic and needs iron supplements
- B. The test determines if there is excess glucose building up in the urine
- C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
- D. The test determines the amount of hemoglobin that is coated with glucose
Correct answer: D
Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.
