Nursing Elites

1. A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:

• A. increased therapeutic effects of Drug A.
• B. increased adverse effects of Drug B.
• C. decreased therapeutic effects of Drug A.
• D. decreased therapeutic effects of Drug B.

Correct answer: C

Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.

2. A patient has suffered a left CVA and developed severe hemiparesis resulting in a loss of mobility. The nurse notices on assessment that an area over the patient's left elbow appears as non-blanchable erythema, and the skin is intact. The nurse should score the patient as having which of the following?

• A. Stage I pressure ulcer
• B. Stage II pressure ulcer
• C. Stage III pressure ulcer
• D. Stage IV pressure ulcer

Correct answer: A

Rationale: Erythema with the skin intact is characteristic of a Stage I pressure ulcer. At this stage, the skin is not broken, but there is localized redness that does not blanch when pressed. Stage II pressure ulcers involve partial-thickness skin loss, Stage III pressure ulcers have full-thickness skin loss, and Stage IV pressure ulcers extend to deeper tissues, including muscle and bone. In this case, the non-blanchable erythema with intact skin aligns with the characteristics of a Stage I pressure ulcer.

3. When a client informs the nurse that he is experiencing hypoglycemia, the nurse provides immediate intervention by providing:

• A. one commercially prepared glucose tablet
• B. two hard candies
• C. 4-6 ounces of fruit juice
• D. 2-3 teaspoons of honey

Correct answer: D

Rationale: The correct immediate intervention for hypoglycemia is to provide 10-15 grams of fast-acting simple carbohydrates orally if the client is conscious and able to swallow. This can be achieved by giving 2-3 teaspoons of honey. Honey is a quick source of simple sugars that can rapidly raise blood glucose levels. Commercially prepared glucose tablets or 4-6 ounces of fruit juice are also appropriate options. However, adding sugar to fruit juice is unnecessary as the natural fruit sugar in juice already provides enough simple carbohydrates to raise blood glucose levels. Hard candies are not the best choice for immediate intervention in hypoglycemia as they may not provide a sufficient amount of fast-acting carbohydrates needed to raise blood sugar levels quickly.

4. A healthcare professional is assessing a patient in the rehab unit during shift change. The patient has sustained a TBI 3 weeks ago. Which of the following is the most distinguishing characteristic of a neurological disturbance?

• A. LOC (level of consciousness)
• B. Short-term memory
• C. Babinski sign
• D. Clonus sign

Correct answer: A

Rationale: Level of consciousness (LOC) is the most crucial indicator of impaired neurological function. Changes in LOC can signify various neurological conditions, including traumatic brain injury. Short-term memory, while important, is not the most distinguishing characteristic of neurological disturbances. Babinski and Clonus signs are specific neurological tests that can provide information about upper motor neuron lesions but are not as generalizable as changes in LOC for assessing overall neurological status.

5. Jane Love, a 35-year-old gravida III para II at 23 weeks gestation, is seen in the Emergency Department with painless, bright red vaginal bleeding. Jane reports that she has been feeling tired and has noticed ankle swelling in the evening. Laboratory tests reveal a hemoglobin level of 11.5 g/dL. After evaluating the situation, the nurse determines that Jane is at risk for placenta previa, based on which of the following data?

• A. anemia
• B. edema
• C. painless vaginal bleeding
• D. fatigue

Correct answer: C

Rationale: Placenta previa is a disorder where the placenta implants in the lower uterine segment, causing painless bleeding in the third trimester of pregnancy. The bleeding results from tearing of the placental villi from the uterine wall as the lower uterine segment contracts and dilates. It can be slight or profuse and can include bright red, painless bleeding. While anemia (choice A) may be a consequence of chronic bleeding from placenta previa, it is not a direct indicator. Edema (choice B) and fatigue (choice D) are nonspecific symptoms that can occur in pregnancy but are not specific to placenta previa.
