NCLEX PN Exam Cram
1. A healthcare professional is reviewing a patient's ECG report. The patient exhibits a flat T wave, depressed ST segment, and short QT interval. Which of the following medications can cause all of the above effects?
- A. Morphine
- B. Atropine
- C. Procardia
- D. Digitalis
Correct answer: D
Rationale: The correct answer is Digitalis. Digitalis is known to cause a flat T wave, depressed ST segment, and a short QT interval on an ECG report. These ECG changes are characteristic of digitalis toxicity. Morphine is not typically associated with these ECG changes. Atropine is more commonly linked to increasing heart rate rather than causing these specific ECG abnormalities. Procardia is a calcium channel blocker that does not typically produce the described ECG findings. Therefore, Digitalis is the most likely medication causing these effects in the patient.
2. In alcoholics with anemia:
- A. Pernicious anemia is more common than folic acid deficiency.
- B. Iron deficiency and folic acid deficiency can coexist.
- C. The alcohol interferes with iron absorption.
- D. Oral vitamin replacement is contraindicated.
Correct answer: B
Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.
3. A physician orders a serum creatinine for a hospitalized client. The nurse should explain to the client and his family that this test:
- A. is normal if the level is 4.0 to 5.5 mg/dl.
- B. can be elevated with increased protein intake.
- C. is a better indicator of renal function than the BUN.
- D. reflects the fluid volume status of a person
Correct answer: C
Rationale: A serum creatinine level should be 0.7 to 1.5 mg/dl, and it does not vary with increased protein intake, so it is a better indicator of renal function than the BUN. Choice A is incorrect as a serum creatinine level of 4.0 to 5.5 mg/dl is not normal. Choice B is incorrect as serum creatinine is not affected by increased protein intake. Choice D is incorrect as serum creatinine primarily reflects renal function, not fluid volume status.
4. Which of the following classifications of medications is used to help decrease tremors for clients with hyperthyroidism?
- A. Steroids
- B. Anticonvulsants
- C. Beta blockers
- D. Iodine compounds
Correct answer: C
Rationale: The correct answer is Beta blockers. Beta blockers are commonly used to help decrease tremors in clients with hyperthyroidism by blocking the action of adrenaline. This helps to control symptoms such as rapid heart rate, tremors, and anxiety. Steroids (Choice A) are not typically used to treat tremors in hyperthyroidism. Anticonvulsants (Choice B) are primarily used to control seizures and are not the first-line treatment for tremors in hyperthyroidism. Iodine compounds (Choice D) are used in the treatment of hyperthyroidism by reducing the production of thyroid hormones but are not specifically indicated for tremor relief.
5. A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?
- A. The patient may be developing CHF
- B. The patient may be having a MI
- C. The patient may be developing COPD
- D. The patient may be having an onset of PVD
Correct answer: B
Rationale: In this scenario, the patient's symptoms of shortness of breath (SOB) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness. Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or peripheral vascular disease (PVD).
