Nursing Elites

1. Which of the following describes passive immunity?

• A. Vaccination against the disease
• B. Transfer of antibodies from mother to baby
• C. Cuts or wounds that are infected and heal
• D. Having the disease in question

Correct answer: B

Rationale: Passive immunity is the transfer of pre-formed antibodies from one individual to another, providing immediate but temporary protection. In this case, the correct answer is the transfer of antibodies from the mother to the baby, as it describes the concept of passive immunity. Choice A, vaccination against the disease, refers to active immunity where the individual's immune system is stimulated to produce antibodies. Choice C, cuts or wounds that are infected and heal, is unrelated to immunity. Choice D, having the disease in question, does not describe passive immunity but rather acquiring active immunity through exposure to the pathogen.

2. During surgery, the anesthesia personnel notice the client is having a steady rise in end-tidal carbon dioxide level. At this time, the nurse anesthetist begins to assess the client for malignant hyperthermia. The initial (priority) assessment for this disorder may include:

• A. measuring serum potassium levels.
• B. monitoring for muscle rigidity.
• C. evaluating renal function.
• D. checking arterial blood gases.

Correct answer: B

Rationale: The correct answer is B: monitoring for muscle rigidity. Muscle rigidity is a hallmark sign of malignant hyperthermia, a life-threatening condition triggered by certain anesthetics. Monitoring for this sign is critical in the early identification of the condition. Choices A, C, and D are not the initial priority assessments for malignant hyperthermia. Measuring serum potassium levels, evaluating renal function, and checking arterial blood gases are not specific initial assessments for malignant hyperthermia and would not aid in its early identification.

3. A patient taking oral contraceptives reports breakthrough bleeding. What should the nurse assess in this patient?

• A. Adherence to the medication schedule
• B. The possibility of pregnancy
• C. The need for an increased dosage
• D. The effectiveness of the current oral contraceptive

Correct answer: A

Rationale: When a patient on oral contraceptives experiences breakthrough bleeding, the nurse should assess the patient's adherence to the medication schedule. Breakthrough bleeding can be a sign of missed doses or inconsistent timing, which can decrease the effectiveness of oral contraceptives. Assessing the patient's adherence helps in ensuring proper use of the medication. Choices B, C, and D are incorrect because breakthrough bleeding is more likely related to adherence issues rather than pregnancy, the need for increased dosage, or the effectiveness of the current oral contraceptive.

4. In a male patient with benign prostatic hyperplasia (BPH) prescribed tamsulosin (Flomax), what is the expected therapeutic effect of this medication?

• A. Decreased urinary frequency and urgency
• B. Increased urinary output
• C. Decreased blood pressure
• D. Increased hair growth

Correct answer: A

Rationale: The correct answer is A: Decreased urinary frequency and urgency. Tamsulosin is prescribed for patients with BPH to relax the muscles in the prostate and bladder neck. This relaxation helps in relieving the symptoms of BPH, such as decreased urinary flow, frequent urination, and urgency. Choice B is incorrect because tamsulosin does not increase urinary output but rather improves the flow of urine by relaxing the muscles. Choice C is incorrect as tamsulosin is not primarily used for reducing blood pressure. Choice D is also incorrect as tamsulosin does not promote increased hair growth.

5. What are the major mechanisms of spinal cord injuries?

• A. Hypoextension, expansion, hyperflexion
• B. Hyperflexion, expansion, hypometabolism
• C. Hypermetabolism, compression, hyperextension
• D. Hyperextension, hyperflexion, compression

Correct answer: D

Rationale: The correct answer is D. Spinal cord injuries commonly occur due to hyperextension, hyperflexion, and compression. Hyperextension and hyperflexion refer to the excessive bending or stretching of the spinal cord, while compression is the exertion of pressure on the spinal cord. These mechanisms can lead to damage such as contusions, lacerations, and compression of the spinal cord. Choices A, B, and C are incorrect as they do not accurately represent the major mechanisms of spinal cord injuries.
