NCLEX PN Exam Cram
1. The PN is caring for a client with diabetes insipidus. The nurse can expect the lab work to show:
- A. elevated urine osmolarity and elevated serum osmolarity.
- B. decreased urine osmolarity and decreased serum osmolarity.
- C. elevated urine osmolarity and decreased serum osmolarity.
- D. decreased urine osmolarity and elevated serum osmolarity.
Correct answer: D
Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.
2. 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).
3. The charge nurse is observing a student nurse caring for a 4-month-old infant in isolation diagnosed with RSV. Which of the following would indicate to the charge nurse that the student nurse needs further instruction on isolation standards?
- A. Donning clean gloves each time she goes in the room.
- B. Wearing a clean mask each time she goes in the room.
- C. Labeling the door so staff will use Airborne Precautions.
- D. Wearing a gown when she goes in the room to administer medication.
Correct answer: A
Rationale: The correct answer is 'Donning clean gloves each time she goes in the room.' Sterile gloves are not necessary for standard isolation precautions; clean gloves are sufficient. The student nurse should be instructed to use clean gloves to reduce the risk of spreading infections. Wearing a clean mask each time she goes in the room is a good practice to prevent the spread of respiratory infections like RSV. Labeling the door for Airborne Precautions is appropriate for RSV. Wearing a gown when entering the room to administer medication helps prevent the transmission of infectious agents.
4. The nurse should plan to evaluate the earliest onset of effectiveness of nitroglycerin (Nitrostat) sublingual (SL) within what time frame?
- A. 15 seconds
- B. 3 minutes
- C. 5 minutes
- D. 15 minutes
Correct answer: B
Rationale: The onset of action for Nitrostat SL is 1 to 3 minutes. Therefore, the nurse should plan to evaluate the earliest onset of effectiveness within 3 minutes after administering the medication. Option A, 15 seconds, is too short of a time frame for the onset of action of Nitrostat. Option C, 5 minutes, is slightly delayed compared to the typical onset time. Option D, 15 minutes, is too long to wait for evaluating the effectiveness of Nitrostat sublingual administration.
5. A patient has been admitted to the hospital with an L4-5 HNP diagnosis. After 24 hours, the patient is able to ambulate with assistance and has reduced muscle spasms. Which of the following medications was the most beneficial in changing the patient's mobility status?
- A. Mivacron
- B. Atropine
- C. Bethanechol
- D. Flexeril
Correct answer: D
Rationale: The correct answer is Flexeril. Flexeril is a muscle relaxant commonly used to treat acute muscle pain and spasms. In this scenario, the patient experiencing reduced muscle spasms and improved mobility after taking Flexeril indicates its effectiveness. Choice A, Mivacron, is a neuromuscular blocking agent that is not typically used for muscle spasms or pain relief. Choice B, Atropine, is a medication used to treat certain types of nerve agent and pesticide poisonings, not muscle spasms. Choice C, Bethanechol, is a medication that stimulates bladder contractions and is not indicated for muscle spasms or mobility improvement.
