1. Low birth weight is defined as a newborn's weight of:

A. 2500 grams or less at birth, regardless of gestational age.
B. 1500 grams or less at birth, regardless of gestational age.
C. 2500 grams or less at birth, according to gestational age.
D. 1500 grams or less at birth, according to gestational age.

Correct answer: A

Rationale: Low birth weight is defined as 2500 grams or less at birth, regardless of gestational age. This means that any newborn weighing 2500 grams or less is considered to have a low birth weight, irrespective of how many weeks they were in the womb. Choices B, C, and D are incorrect because they specify a weight of 1500 grams or less, which is not the standard definition of low birth weight. The correct definition is 2500 grams or less, not influenced by gestational age.

2. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

A. ST depression
B. Inverted T wave
C. Prominent U wave
D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

3. Your patient has been diagnosed with orchiditis. What information about this disorder should you inform the patient about?

A. This disorder often occurs as a result of streptococcus.
B. This disorder can be symptomatically treated with ice.
C. This disorder can be symptomatically treated with heat.
D. This disorder is typically treated with surgery.

Correct answer: B

Rationale: Orchiditis can be symptomatically treated with ice to reduce inflammation. Choice A is incorrect because orchiditis is not typically caused by streptococcus. Choice C is incorrect as heat is not the recommended treatment for orchiditis. Choice D is also incorrect as surgery is not the first-line treatment for orchiditis.

4. Which of the following is the best argument for lower patient-to-nurse ratio?

A. The more patients a nurse has, the better the nurse will be at catching early warning signs.
B. Greater patient-to-nurse ratios decrease patient mortality.
C. Adequate nurse levels do not impact the prevalence of urinary tract infections.
D. Community nursing ratios do not impact Methicillin-resistant Staphylococcus aureus (MRSA) rates.

Correct answer: B

Rationale: The best argument for lower patient-to-nurse ratios is that they decrease patient mortality. Choice A is incorrect because having more patients can lead to increased workload and decreased attention per patient. Choice C is incorrect as adequate nurse levels can indeed impact the prevalence of infections. Choice D is incorrect as community nursing ratios can impact MRSA rates due to potential transmission risks in healthcare settings.

5. What does the mnemonic PERLA stand for in the assessment of the eyes?

A. Pupils equally reactive to light and accommodation
B. Patient eyes are equally recessed and responsive to light and acuity
C. Patient eyes are equally responsive to light and acuity
D. Pupils equally reactive to light and acuity

Correct answer: A

Rationale: The correct answer is A: 'Pupils equally reactive to light and accommodation.' PERLA is a mnemonic used in eye assessments to check for Pupils being equally reactive to Light and Accommodation. Choice B is incorrect as it includes irrelevant information about the eyes being recessed. Choice C is incorrect as it is missing the mention of pupils and accommodation. Choice D is incorrect as it misses the mention of accommodation.
